XORWF Exclusive OR W with f
Syntax: XORWF f {,d {,a}}
Operands: 0
 f  255
d
 [0,1]
a
 [0,1]
Operation: (W) .XOR. (f)
dest
Status Affected: N, Z
Encoding:
0001 10da ffff ffff
Description: Exclusive OR the contents of W with
register ‘f’. If ‘d’ is ‘
0’, the result is stored
in W. If ‘d’ is ‘
1’, the result is stored back
in the register ‘f’.
If ‘a’ is ‘
0’, the Access Bank is selected.
If ‘a’ is ‘
1’, the BSR is used to select the
GPR bank.
If ‘a’ is ‘
0’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f
95 (5Fh). See
Section 29.2.3 “Byte-Oriented and
Bit-Oriented Instructions in Indexed
Literal Offset Mode”
for details.
