IPC: G04G5/00
Filed: 1982-07-08
Abstract: PURPOSE:To correct a time error of a clock circuit without depending on a person's help, by calculating the time error from a difference between an initial set time and a present time, and correcting a time data of a timer 1 in accordance with its result. CONSTITUTION:When it is decided that an error is generated in a time data, an operator inputs a correct time data from a keyboard, etc. As a result, a CPU 3 designates an address in which an initial set time data T1 is stored, to a non- volatile memory 2 through a bus 4, and reads out a data stored in this address. An error E of the time data is derived from a difference between the initial set time data T1 and a reset time data T2, and in accordance with this calculated error value, the time of the timer 1 is set once again. Also, the reset time data T2 is added and stored in the non-volatile memory 2, is prepared for another correction.

Filed: 1989-05-11
Abstract: PURPOSE:To detect the designated conditions in real time by providing plural registers, counters and comparators which can be set with instructions and supporting the program debug in a real time executing state. CONSTITUTION:An address is designated to a designated address decoder 23 and at the same time the number of times of execution is designated to a break count register 22 via a monitor program. A microprocessor 1 compares the address value designated by the decoder 23 with the value of an address TAG memory 4 corresponding to the instruction of an instruction cache which is read out by an executing unit 5. When the coincidence is obtained between both values, the processor 1 outputs a coincidence detection signal to a specific address counter 20. The counter 20 counts the coincidence signals. A comparator 21 compares the value set previously at the counter 20 with the counted value of the counter 20. When the coincidence is obtained between both values, the comparator 21 outputs an internal interruption signal (e) and executes the monitor program. The monitor program can support the program debug when the signal (e) is produced.

Title: Output buffer circuit
Inventor: SUGIYAMA NOBUYUKI
IPC: H03K19/0948

Abstract: PURPOSE:To suppress a through current and to reduce a current consumption, by providing an ON/OFF control circuit so that first and second transistors in an output circuit can be set at de-energized states simultaneously once in a transient state where the ON and the OFF of an input signal are switched. CONSTITUTION:When the input signal V1 changes from a high level to a low level, an output signal V2 goes to the high level first by a NAND circuit 22, and the transistor Q1 is set at a cut-off state, and when the output signal V1 goes to the low level after a prescribed time being delayed, an output signal V3 goes to the high level by a NOR circuit 23, and the transistor Q2 is set at an energized state. Thus, by increasing a delay time (for example, larger than the delay time of the NAND circuit 22 or the NOR circuit 23) to some extent by a delay circuit 21, it follows that either the transistors Q1 or Q2 on the other side is set at the energized state after either the transistors on one side is set at the cut-off state when the input signal V1 changes from the ON to the OFF or from the OFF to the ON. In such a way, it is possible to eliminate the through current IT.
