RLNCF

Rotate Left f (no carry)

Syntax:

[ label ] RLNCF

f [,d [,a]]

Operands:

≤ f ≤ 255

∈ [0,1]

Operation:

(f<n>)

→ dest<n+1>,

(f<7>)

→ dest<0>

Status Affected:

N,Z

Encoding:

0100

01da

ffff

Description:

The contents of register ’f’ are

rotated one bit to the left. If ’d’ is 0

the result is placed in WREG. If ’d’ is

1, the result is stored back in register

'f' (default). If ’a’ is 0, the Access

Bank will be selected, overriding the

BSR value. If ’a’ is 1, the Bank will

be selected as per the BSR value.

RRCF

Rotate Right f through Carry

Syntax:

[ label ]

RRCF f [,d [,a]]

Operands:

≤ f ≤ 255

∈ [0,1]

Operation:

(f<n>)

→ dest<n-1>,

(f<0>)

→ C,

(C)

→ dest<7>

Status Affected:

C,N,Z

Encoding:

0011

00da

ffff

Description:

The contents of register 'f' are

rotated one bit to the right through

the Carry Flag. If 'd' is 0, the result is

placed in WREG. If 'd' is 1, the result

is placed back in register 'f' (default).

If ’a’ is 0, the Access Bank will be

selected, overriding the BSR value.

If ’a’ is 1, the Bank will be selected

as per the BSR value.
