PIC16F5X

XORLW Exclusive OR literal with W

Syntax: [ label ]XORLW k

Operands: 0 ≤ k ≤ 255

Operation: (W) .XOR. k → (W)

Status Affected: Z

Encoding: 1111 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

Words: 1

Cycles: 1

Example

: XORLW 0xAF

Before Instruction

W=0xB5

After Instruction

W=0x1A

XORWF Exclusive OR W with f

Syntax: [ label ] XORWF f, d

Operands: 0 ≤ f ≤ 31

d ∈ [0,1]

Operation: (W) .XOR. (f) → (dest)

Status Affected: Z

Encoding: 0001 10df ffff

Description: Exclusive OR the contents of the

W register with register ‘f’. If ‘d’ is

‘0’, the result is stored in the W

stored back in register ‘f’.

Words: 1

Cycles: 1

Example

: XORWF REG,1

Before Instruction

REG = 0xAF

W=0xB5

After Instruction

REG = 0x1A

W=0xB5
