XORWF

Exclusive OR W and f

Syntax

XORWF f, d

Operation

W XOR M (f) => (destination)

Status Affected

Z

Description

Exclusive OR the content of the W register and M (f). If d is 0, the result is stored

in the W register. If d is 1, the result is stored back in M (f).

RLF

Rotate left M (f) through Carry

Syntax

RLF

f, d

Operation

M (f) [6:0], C => (destination)

Status Affected

C

Description

M (f) is rotated one bit to the left through the Carry bit. If d is 0, the result is stored

in the W register. If d is 1, the result is stored back in M (f).

SUBWFC

Subtract W and Carry from f

Syntax

SUBWFC f, d

Operation

M (f) + NOT (W) + C => (destination)

Status Affected

DC, C, Z

Description

Subtract the content of the W register from M (f). If d is 0, the result is stored in the

W register. If d is 1, the result is stored back in M (f).

RRF

Rotate right M (f) through Carry

Syntax

RRF

f, d

Operation

C, M (f) [7:1] => (destination)

Status Affected

C

Description

M (f) is rotated one bit to the right through the Carry bit. If d is 0, the result is stored

in the W register. If d is 1, the result is stored back in M (f).
