XORLW - Exclusive OR literal with W
Syntax: [label] XORLW k
Description: The content of register W is XOR’ed with the 8-bit literal k . The result is
stored in register W.
Operation: (W) .XOR. k -> W
Operand: 0 k 255
Status affected: Z
Number of cycles: 1
EXAMPLE 1:
....
[label] XORLW 0xAF
Before instruction execution: W = 0xB5 ; 1011 0101 (0xB5)
; 1010 1111 (0xAF)
------------------
After instruction: W = 0x1A ; 0001 1010 (0x1A)
Z = 0
EXAMPLE 2:
Const equ 0x37
[label] XORLW Const
Before instruction execution: W=0xAF ; 1010 1111 (0xAF)
Const = 0x37 ; 0011 0111 (0x37)
-------------------------------
After instruction: W = 0x98 ; 1001 1000 (0x98)
Z = 0
