RRA [m]

Rotate right-place result in the accumulator

Description

Data in the specified data memory is rotated one bit right with bit 0 rotated

into bit 7, leaving the rotated result in the accumulator. The contents of the

data memory remain unchanged.

Operation

ACC.(i)

← [m].(i+1); [m].i:bit i of the data memory (i=0-6)

ACC.7

← [m].0

RRC [m]

Rotate data memory right through carry

Description

The contents of the specified data memory and the carry flag are together

rotated one bit right. Bit 0 replaces the carry bit; the original carry flag is

rotated into the bit 7 position.

Operation

[m].i

← [m].(i+1); [m].i:bit i of the data memory (i=0-6)

[m].7

← C

← [m].0

RRCA [m]

Rotate right through carry-place result in the accumulator

Description

Data of the specified data memory and the carry flag are rotated one bit right.

Bit 0 replaces the carry bit and the original carry flag is rotated into the bit

7 position. The rotated result is stored in the accumulator. The contents of

the data memory remain unchanged.

Operation

ACC.i

← [m].(i+1); [m].i:bit i of the data memory (i=0-6)

ACC.7

← C

← [m].0
