RLA [m]
Rotate Data Memory left with result in ACC
Description The contents of the specied 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.
Operation ACC.(i+1) ← [m].i; (i=0~6)
ACC.0 ← [m].7
Affected ag(s) None
RLC [m]
Rotate Data Memory left through Carry
Description The contents of the specied Data Memory and the carry ag are rotated left by 1 bit. Bit 7
replaces the Carry bit and the original carry ag is rotated into bit 0.
Operation [m].(i+1) ← [m].i; (i=0~6)
[m].0 ← C
C ← [m].7
Affected ag(s) C
RLCA [m]
Rotate Data Memory left through Carry with result in ACC
Description Data in the specied Data Memory and the carry ag are rotated left by 1 bit. Bit 7 replaces the
Carry bit and the original carry ag is rotated into the bit 0. The rotated result is stored in the
Accumulator and the contents of the Data Memory remain unchanged.
Operation ACC.(i+1) ← [m].i; (i=0~6)
ACC.0 ← C
C ← [m].7
Affected ag(s) C
RR [m]
Rotate Data Memory right
Description The contents of the specied Data Memory are rotated right by 1 bit with bit 0 rotated into bit 7.
Operation [m].i ← [m].(i+1); (i=0~6)
[m].7 ← [m].0
Affected ag(s) None
RRA [m]
Rotate Data Memory right with result in ACC
Description Data in the specied Data Memory is 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.
Operation ACC.i ← [m].(i+1); (i=0~6)
ACC.7 ← [m].0
Affected ag(s) None
RRC [m]
Rotate Data Memory right through Carry
Description The contents of the specied Data Memory and the carry ag are rotated right by 1 bit. Bit 0
replaces the Carry bit and the original carry ag is rotated into bit 7.
Operation [m].i ← [m].(i+1); (i=0~6)
[m].7 ← C
C ← [m].0
Affected ag(s) C
