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
C
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
C
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.
