Version 1.1(e) Test PCD Antenna tuning
A two step simple phase tuning procedure is used to match the impedance of the antenna to that ofthe driving generator. After the two steps of the tuning procedure the signal generator shall bedirectly connected to the antenna output for the tests.
Step 1:
A high precision resistor of 50 Ohm ± 1 % (e.g. 50 Ohm BNC resistor) is inserted in the signal line
between the signal generator output and an antenna connector. The two probes of theoscilloscope are connected to both sides of the serial reference resistor. The oscilloscope displays
a Lissajous figure when it is set in Y to X presentation.
The signal generator is set to:
Wave form: Sinusoidal
Frequency: 13.56 MHz
Amplitude: 2V (rms) - 5V (rms)
The probe, which is in parallel to the output connector has a small parasitic capacitance Cprobe. A
calibration capacitance Ccal in parallel to the output connector compensates this probe capacitor if
Ccal = Cprobe. The output is terminated with a second high precision resistor of 50 Ohm ± 1 % (e.g.
50 Ohm BNC terminating resistor). The probe capacitor is compensated when the Lissajous
figure is completely closed.
The adjustment method is shown in "Fig. 14.2-8 Calibration set-up - Step1".

14.3.1.1 Functional Tests(1) Basic Specifications
This test measures the amplitude of the load modulation signal of the PICC within the operating
magnetic field region defined by the PCD.
(a) Test Method
Step 1:The load modulation test circuit shown in "Fig. 14.2-3 Load Modulation Measuring Circuit" andthe test PCD shown in "Fig. 14.2-4 Test PCD Assembly" are used.
Adjust the current in the PCD antenna to the required field strength as measured by the calibrationcoil. Connect the output of the load modulation test circuit of "Fig 14.2-3 Load Modulation
Measuring Circuit" to the digitizing sampling oscilloscope. The 50 Ohm potentiometer shall be
trimmed to minimize the residual carrier. This signal shall be at least 40dB lower than the signal
obtained by shorting one sense coil.
(Note: The waveform of the load modulated subcarrier (fc) is measured with a digitizing sampling
oscilloscope capable of sampling at a rate of 100 million samples per second with a resolution of 8
bits at optimum scale.)
Step 2:The PICC under test shall be placed in the DUT position, concentric with sense coil a. The RF
drive into the test PCD antenna shall be re-adjusted to the required field strength.
Display a segment of at least two cycles of the waveform of the subcarrier load modulation on thedigital sampling oscilloscope and store the sampled data in a file for analysis by a computer
software programme.
Fourier transform exactly two subcarrier cycles of the sampled modulation waveform using suitablecomputer software.

Use a discrete Fourier transformation with a scaling such that a puresinusoidal signal results in its peak magnitude. To minimize transient effects, avoid a subcarrier
cycle immediately following a non-modulation period.
The resulting peak amplitudes of the upper and lower sidebands at fc +fs and fc –fs shall be above
the value defined in "10.1.2 Load Modulation".
A REQA or a REQB command sequence as define in "12. Anticollision" shall be sent by the Test

16.2Block Format
Communication between an upper device and PCD is performed in block units. Blocks arealways sent by the upper device to the PCD first. Blocks sent from the upper device to the PCD
are referred to as command blocks or commands.
When the PCD receives a command block from an upper device, it processes the command blockand, as a general rule, returns the results to the upper device. Blocks sent from the PCD to theupper device are referred to as response blocks or simply as responses.
The format of command blocks and response blocks is shown in "Fig. 16.2-1 Block Format".
Items surrounded by brackets "[ ]" in the figure indicate optioned items, and may not betransmitted depending on block contents. Items surrounded by parentheses "( )" in the figure
represent the number of bytes for that item. Blocks are transmitted from left to right in the figureduring block transmission.

16.2.2 LEN (Required)
LEN consists of two bytes of data that indicate the size of the DAT portion in a transmitted block.
LEN has a value of 0000h to 0103h, and the upper byte is transmitted first.
When the PCD receives a command block from an upper device, the first three bytes are received
as RCB and LEN. Next, data of the number of bytes indicated with LEN is read as DAT, and thenext byte is processed as BCC.
If BCC is judged as normal, the contents of the received command block are interpreted andprocessing is carried out.
If the value of LEN in a command block is greater than the actual size of the DAT portion, thePCD judges that the data has been interrupted during the course of receiving. When this happens,
the PCD shall return a response block indicating a CWT error to the upper device.
In addition, in the case the value of LEN is 0104h or more and the length of the DAT portion
actually received is 0104h or more, the amount of received data may overflow from the receive
buffer of the PCD. When this happens, PCD shall return a response block indicating a receive
buffer overflow error to the upper device.

326

Version 1.1

16.2.3 DAT (Optional)
DAT is data of variable length that indicates the main body of a command or response.
DAT encoding are defined in "16.5 Commands and Responses".

Details of

DAT is optional and there are blocks that do not contain DAT. Blocks without DATs are, resend
response request blocks character receive error blocks, CWT error blocks, receive buffer overflow
blocks and BCC error blocks. B8 of RCB is set to '1' in these blocks. (For details, refer to"16.2.1 RCB (Required)".

327

Version 1.1

16.2.4 BCC (Required)
BCC is a single byte of data that indicates the block check code. The value of BCC is encoded sothat the bitwise exclusive OR with RCB will result in a valie of 00h.
If the result of calculating BCC is other than 00h, the PCD judges that receiving of the command
block has failed. When this happens, the PCD sends a response block indicating a BCC error to
the upper device.

16.3.1 Character Waiting Time (CWT)
The maximum delay time between two consecutive characters within a single block is shown in"Table 16.3-1 Character Waiting Time (CWT)". If the amount of time between two consecutive
characters while receiving a block exceeds CWT, an inter-character timeout occurs.
If the PCD detects an inter-character timeout while receiving a command block from an upperdevice, it returns a CWT error block to the upper device.
Recommended processing when the upper device detects an inter-character timeout while
receiving a response block from the PCD consists of interrupting the receive processing andsending a resend request block .

16.3.2 Block Guard Time (BGT)
Block guard time (BGT) is the shortest amount of time between two consecutive blocks along thetransmission path between an upper device and PCD. If the next block is transmitted before BGT
has elapsed, that block is not guaranteed.
The following three types of BGT are defined.
- BGTUR: Shortest amount of time until the PCD sends a response block in response to acommand block from an upper device- BGTRU: Shortest amount of time until an upper device sends a command block in response to a
response block from the PCD- BGTUU: Shortest amount of time to send command blocks consecutively from an upper device.
These specifications are not applied in cases where a response block from the PCD is present
between consecutive command blocks.

(See "16.4.1 (6) Consecutive Command Receive

Error")The value of each BGT is shown in "Table 16.3-2 Block Guard Time (BGT)".

following completion of transmission of a command block from an upper device is shown in"Table 16.3-3 Block Waiting Time (BWT)". If the amount of time until the start of blockreceiving exceeds BWT, an inter-block timeout occurs. Refer to "16.4.2(3) Receive Timeout(BWT)" for information on processing when the upper device detects an iner-block timeout.
BWT can have three types of values depending on the type of RCB of the command block sentfrom the upper device.

16.4Communication Error Processing
Processing by the PCD and processing by the upper device when an error occcurs duringcommunication between the upper device and PCD are as described below.
16.4.1 PCD Communication Error Processing
The processing of the PCD when a receive error occurs in the PCD is as described below.
(1) Character Receive Error
If there is an error in a character received by the PCD (such as a parity error, framing error or
overrun), a character receive error occurs.
If the PCD has succesfully received data through LEN, a character receive error block is returnedto the upper device following reception through BCC. If a character receive error occurs during
reception of RCB or LEN, the PCD treats this as receiving noise, discards the portion it hasreceived up to that point, and repeats reception from the beginning.
(2) CWT Error
If an inter-character timeout occurs while there is data still remaining to be received, a CWT error
occurs. If the PCD has succesfully received data through LEN, an CWT error block isimmediately returned to the upper device. If the an error occurred prior to receiving LEN, thePCD treats this as receiving noise and repeats reception from the beginning.
(3) Receive Buffer Overflow
If the data received exceeds the capacity of the receive buffer of the PCD, a receive buffer
overflow occurs. When a receive buffer overflow occurs, the PCD discards all received data andimmediately returns a receive buffer overflow block to the upper device.
(4) BCC Error
The PCD performs a BCC check after receiving data through BCC. If the calculated value of
BCC is in error (other than 00h), a BCC error occurs. When a BCC error occurrs, the PCD
discards all received data and immediately returns a BCC error block to the upper device.

333

Version 1.1(5) Received Data Amount Error
If additional data is received after receiving data through BCC, a received data amount error occurs.
When a received data amount error occurs, the PCD performs processing ignoring all the data
received after the error. Namely, processing for the received command block is performed if thecontents of that command block are normal.
However, the operation of the PCD is not guaranteed when consecutive data is received by the
PCD beyond BGTUR.
(6) Consecutive Command Receive Error
Since communication between an upper device and the PCD is half-duplex, the upper device, as a
general rule, sends the next command block after having received a response block from the PCD.
However, there are cases in which the PCD does not return a response to the upper device forreasons such as a receive error in the PCD or while waiting for a response from a PICC.
In such cases, if a command block is sent from the upper device on or after BGTUU, the PCD
discontinues processing up to that point and performs processing for receiving a new command
block. The PCD only sends a response block in response to a new command block and will not
send a response block for the processing that was discontinued.
If the PCD receives data prior to BGTUU, a consecutive command receive error occurs.
operation of the PCD is not guaranteed when a consecutive command receive error occurrs.

334

The

Version 1.1

16.4.2 Upper Device Communication Error Processing
The recommended processing by an upper device when a communication error has been detectedin the upper device is as described below.
(1) Receive Error
If some type of error is detected in a response block received from a PCD (such as a character
receive error, CWT error or BCC error), a receive error occurs.
If a receive error has been detected in the upper device, a resend response request block is sent to
the PCD. When the PCD receives this block, it resends the latest response block that was sent.
If a receive error is detecte again in the response to resend response request block, the manager ofthe upper device shall verify the communication line since there is the possibility of an error in thecommunication line between the upper device and PCD.
(2) Error Response Received
If a response received from the PCD is a block that indicates a command block receive error in the
PCD (character receive error block, CWT error block or BCC error block), an error response
receival occurs.
When an error resonse receival is detected in the upper device, the same as the command blockpreviously sent is resent to the PCD is resended.
If a response error is detected again in response to the resent command, the manager of the upperdevice shall verify the communication line since there is the possibility of an error in thecommunication line between the upper device and PCD.

335

Version 1.1(3) Receive Timeout (BWT)
If there is no response from the PCD after BWT has elapsed, a receive timeout (BWT) error
occurs.
When a receive timeout (BWT) is detected in the upper device, the following processing is
performed according to the type of RCB of the command block that was sent.
- If a command for a PICC was sent:
A PICC communication error is assumed to have occurred, and a command is resent according
to the protocol of the PICC.
Refer to "13. Transmission Protocol" for details regarding the procedure for resending
commands to a PICC.
- If a command for the PCD was sent:
There is the possibility that communication itself may not have been possible. If a receive
timeout occurrs again after resending the command, check whether or not the power supply to
the PCD is normal, and whether an anomaly has occurred in the communication line.
(In the case of a PCD self-diagnostic command, since specifications are such that a response
block is not returned from the PCD, detection of a receive time out (BWT) must not be
performed by the upper device.)- If a resend request response was sent:
There is the possibility that communication itself may not have been possible. If a receive
timeout occurrs again after resending the command, check whether or not the power supply to
the PCD is normal, and whether an anomaly has occurred in the communication line.

336

Version 1.1

16.5Commands and Responses
Commands are divided into commands for a PICC, commands for the PCD, and resend response
request according to the value of RCB. The following provides a description of commands for
PICC and commands for PCD along with their responses.
16.5.1 Commands and Response for PICC
If the value of b8 and b7 of RCB of a command block sent from an upper device is 0, thecommand is for a PICC.
When the case the PCD has normally received a command for a PICC, processing is performed
according to the procedure described below.
1) The DAT portion of the received command block is set in a buffer for sending to the PICC.
2) The data in the buffer is sent to the PICC according to the communication frame format with
the PICC.
3) A response from the PICC is awaited .
4) When a response is received from the PICC, only the data is extracted from thecommunication frame and set in the receive buffer.
5) The contents of the receive buffer are set in the DAT portion of the response block.
6) RCB, LEN and BCC are calculated, and a response block is sent to the upper device.

337

Version 1.1

When communicating with a PICC using a command for a PICC, the precautions described below
must be taken in the upper device.
- Prior to starting communication with the PICC, the carrier output from the PCD shall be turned
on with a command for the PCD (carrier control command: see "16.5.3 (5) Carrier Control" fordetails).
- Communication conditions between the PCD and PICC are set with a command for the PCD(PICC communication information setting command: see "16.5.3 (6) PICC Communication
Information Setting " for details).
- If CRC is used in communication with a PICC, since CRC is not calculated in the PCD, theCRC that will be sent to the PICC shall be embedded in advance in the DAT portion of thecommand for a PICC. In addition, the CRC received from the PICC shall also be contained in
the response block.
- The PCD waits for a response from the PICC until a response is detected from the PICC.
Consequently, if there is no response from the PICC, the PCD does not return a response blockto the upper device.
- If the PCD detects an error when receiving a command from an upper device, it returns a
receive error response block to the upper device without sending the DAT portion to the PICC.
