CPSE —
CPSE
Operation:
Description:
Example:
dst,src
CPSE compares the source operand (subtracts it from) the destination operand, and skips the next
instruction if the values are equal. Neither operand is affected by the comparison.
The extended accumulator contains the value 34H and register pair HL contains 56H. The second
instruction (RET) in the instruction sequence
CPSE
RET
is not skipped. That is, the subroutine returns since the result of the comparison is 'not equal'.
