User Manual
r identifies registers B, C, D, E, H, L, or A specified in the assembled object code field, as
follows:
Description
The logical exclusive-OR operation is performed between the byte specified by the s oper-
and and the byte contained in the Accumulator; the result is stored in the Accumulator.
Condition Bits Affected
S is set if result is negative; otherwise, it is reset.
Z is set if result is 0; otherwise, it is reset.
H is reset.
P/V is set if parity even; otherwise, it is reset.
N is reset.
C is reset.
Example
If the Accumulator contains
96h
(
1001
0110
), then upon the execution of an XOR
5Dh
(
5Dh
=
0101
1101
) instruction, the Accumulator contains
CBh
(
1100
1011
).
