List Of Input/Output Pin Handling Instructions - NEC PD75402A User Manual

(1) Bit handling instructions
Direct addressing of specific address bits (fmem.bit) can be used on all digital input/output ports.
Example To OR P50 and P31 and output the result to P61.
SET1
AND1
OR1
SKT
BR
SET1
CLRP : CLR1
(2) 4-bit handling instructions
All 4-bit memory handling instructions can be used, such as MOV, XCH, ADDS and INCS, in addition to the IN/
OUT instructions.
Example 1. To output accumulator contents to port 3.
OUT
2. To add the accumulator value to the data output to port 5, and output the result.
