SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER for INFRARED REMOTE CONTROL TRANSMITTERS
LOGIC OPERATION FUNCTION
The 4280 Group has the 4-bit logic operation function. The logic
operation between the contents of register A and the low-order 4
bits of register E is performed and its result is stored in register
A.
Each logic operation can be selected by setting logic operation
selection register LO.
Set the contents of this register through register A with the TLOA
instruction. The logic operation selected by register LO is
executed with the LGOP instruction.
Table 5 shows the logic operation selection register LO.
