XOR A, (IX/Y+d)
Logical Exclusive OR
Operation
A ← A XOR (IX/Y+d)
Description
The ( IX/Y + d ) operand is an 8-bit value at the memory location specified by the contents
of the Index Register, IX or IY, added to the two’s-complement displacement
d . This 8-bit
value is bitwise exclusive-ORed with the contents of the accumulator, A. The result is
written to the accumulator.
Condition Bits Affected
