I/O MCU with USB Interface

Rotate Data Memory left with result in ACC

The contents of the specified Data Memory are rotated left by 1 bit with bit 7

rotated into bit 0. The rotated result is stored in the Accumulator and the contents

of the Data Memory remain unchanged.

ACC.(i+1) ← [m].i; (i = 0~6)

ACC.0 ← [m].7

None

Rotate Data Memory left through Carry

The contents of the specified Data Memory and the carry flag are rotated left by 1

bit. Bit 7 replaces the Carry bit and the original carry flag is rotated into bit 0.

[m].(i+1) ← [m].i; (i = 0~6)

[m].0 ← C

C ← [m].7

Rotate Data Memory left through Carry with result in ACC

Data in the specified Data Memory and the carry flag are rotated left by 1 bit. Bit

7 replaces the Carry bit and the original carry flag is rotated into the bit 0. The

rotated result is stored in the Accumulator and the contents of the Data Memory

remain unchanged.

ACC.(i+1) ← [m].i; (i = 0~6)

ACC.0 ← C

C ← [m].7

Rotate Data Memory right

The contents of the specified Data Memory are rotated right by 1 bit with bit 0

rotated into bit 7.

[m].i ← [m].(i+1); (i = 0~6)

[m].7 ← [m].0

None

Rotate Data Memory right with result in ACC

Data in the specified Data Memory and the carry flag are rotated right by 1 bit

with bit 0 rotated into bit 7. The rotated result is stored in the Accumulator and the

contents of the Data Memory remain unchanged.

ACC.i ← [m].(i+1); (i = 0~6)

ACC.7 ← [m].0

None

Rotate Data Memory right through Carry

The contents of the specified Data Memory and the carry flag are rotated right by

1 bit. Bit 0 replaces the Carry bit and the original carry flag is rotated into bit 7.
