XORWF Exclusive OR W with f
Syntax: [ label ] 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 will be selected,
overriding the BSR value. If ‘a’ is ‘1’,
then the bank will be selected as per
the BSR value.
