The numeration of the pixels is in all cases line by line.
SPI Communication:
Data sampled at rising edge of SCLK, MSB first.
In case of ASIC as master device the frequency of the SCLK_IO is equal to the frequency ofMCLK/2.
HTPA8x8 & HTPA16x16:
The four MSB’s signify the row address of the current pixel, the other bits describe the ADCresult.
HTPA 32x31:
The valid sample cycle numbers are expensed in the least 10 bits. The value runs from 0 to527.
HTPA 64x62:
The valid sample cycle numbers are expensed in the least 11 bits. The value runs from 0 to2047.

The output drivers for SCLK_IO and DATA_IO are enabled by CONT.
If CONT is low the data can be written serially from external controller through DATA_IO.
In that case the external controller has to wait a minimum delay time, until SCLK_IO andDATA_IO output drivers are disabled. After programming, the positive slope of CONT storesthe contents, when the number of SCLK-pulses is equal 16. While the output driver of theASIC is disabled a weak pull up ensures that the SCLK_IO pin is at high level. To execute areset command, the µC has to write a logical “1” to the R-Bit in to configuration andafterwards a “0” into the R-bit, which requires two write cycles in this special case.
