RRF

Rotate

right

[f]

through Carry

Syntax

RRF

f, d

≤ f ≤ FFh

∈ [0,1]

Operation

[Destination<n-1>]

←

[f<n>]

[Destination<7>]

← C

← [f<7>]

Flag Affected

Description

[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 [f].

Cycle

Example:

RRF

OPERAND, 0

Before instruction:

C = 0

OPERAND = 95h

After instruction:

C = 1

W = 4Ah,

OPERAND = 95h

SLEEP

Oscillator stop

Syntax

SLEEP

Operation

CPU oscillator is stopped

Flag Affected

Description

CPU oscillator is stopped.

CPU can be waked up by

external interrupt sources.

Cycle

Example:

SLEEP

After instruction:

PD = 1

TO = 0

If WDT causes wake up,

TO = 1

Please make sure all interrupt flags are

cleared

before

running

SLEEP;

"NOP"

command must follow HALT and SLEEP

commands.

SUBLW

Subtract W from literal

Syntax

SUBLW

≤ k ≤ FFh

Operation

[W]

← k – [W]

Flag Affected

C, DC, Z

Description

Subtract the content of the W

literal "k". The result is stored

in the W register.

Cycle

Example 1:

SUBLW

02H

Before instruction:

W = 01h

After instruction:

W = 01h

C = 1

Z = 0

Example 2:

SUBLW

02H

Before instruction:

W = 02h

After instruction:

W = 00h

C = 1

Z = 1

Example 3:

SUBLW

02H

Before instruction:

W = 03h

After instruction:

W = FFh

C = 0

Z = 0

SUBWF

Subtract W from f

Syntax

SUBWF

f, d

≤ f ≤ FFh

∈ [0,1]

Operation

[Destination]

← [f] – [W]

Flag Affected

C, DC, Z

Description

Subtract the content of the W

result is stored in the W

stored back in [f],

Cycle

Example 1:

SUBWF

OPERAND,

Before instruction:

OPERAND = 33h, W =

01h

After instruction:

OPERAND = 32h

C = 1

Z = 0

Example 2:

SUBWF

OPERAND,

Before instruction:

OPERAND = 01h, W =

01h

After instruction:

OPERAND = 00h

C = 1

Z = 1

Example 3:

SUBWF

OPERAND,

Before instruction:

OPERAND = 04h, W =

05h

After instruction:

OPERAND = FFh

C = 0

Z = 0
