XORLW
Exclusive OR Literal with
WREG
Syntax: [ label ] XORLW k
Operands: 0 k 255
Operation: (WREG) .XOR. k WREG)
Status Affected: Z
Encoding:
1011 0100 kkkk kkkk
Description:
The contents of WREG are XOR’ed
with the 8-bit literal 'k'. The result is
placed in WREG.
Words: 1
Cycles: 1
Q Cycle Activity:
Q1 Q2 Q3 Q4

Write to
WREG
Example:
XORLW 0xAF
Before Instruction
WREG = 0xB5
After Instruction
WREG = 0x1A
XORWF Exclusive OR WREG with f
Syntax: [ label ] XORWF f,d
Operands: 0  f  255
d  [0,1]
Operation: (WREG) .XOR. (f) dest)
Status Affected: Z
Encoding:
0000 110d ffff ffff
Description:
Exclusive OR the contents of WREG
with register 'f'. If 'd' is 0, the result is
stored in WREG. If 'd' is 1, the result is
stored back in the register 'f'.
