XORLW Exclusive OR Literal with W
Syntax: [ label ] XORLW k
Operands: 0 ≤ k ≤ 255
Operation: (W) .XOR. k → (W)
Status Affected: Z
Encoding: 11 1010 kkkk kkkk
Description:
The contents of the W register are
XOR’ed with the eight bit literal 'k'.
The result is placed in the W regis-
ter.

XORWF Exclusive OR W with f
Syntax: [
label ] XORWF f,d
Operands: 0 ≤ f ≤ 127
d ∈ [0,1]
Operation: (W) .XOR. (f) → (dest)
Status Affected: Z
Encoding:
00 0110 dfff ffff
Description:
Exclusive OR the contents of the W
register with register 'f'. If 'd' is 0 the
result is stored in the W register. If 'd'
is 1 the result is stored back in register
'f'.
