Title: Data latch circuit
Inventor: KUMAGAI SHIGEKI
IPC: G06F13/42
Filed: 1985-02-06
Abstract: PURPOSE:To transfer surely the data outputted from the transmission side to the reception side by adding plural latch registers and latch control circuits to a system where data are transferred from the transmission side without detecting the reception timing of the reception side. CONSTITUTION:The 1st latch register 21 latches temporarily the data which are transferred to a peripheral device 20 from a transmission register 11 of a CPU10 serving as the transmission side. In such a case, the latching operation is performed synchronously with the transmission control signal WR outputted from an MPU 14 of the CPU 10 via an I/O port 15. While the 2nd latch register 22 latches the data outputted from the register 21 and outputs them to the device 20. Here the latching operation is carried out synchronously with the latch control signal L outputted from a latch control circuit 23. Thus the CPU 10 can transfer surely the transmission data synchronous with the signal WR to the reception side without detecting the reception timing of the device 20.
