ACC
Rotate data memory left
The contents of the specified data memory are rotated 1 bit left with bit 7 rotated into bit 0.
[m].(i+1)
[m].0
Rotate data memory left and place result in the accumulator
Data in the specified data memory is rotated 1 bit left with bit 7 rotated into bit 0, leaving the
rotated result in the accumulator. The contents of the data memory remain unchanged.
ACC.(i+1)
ACC.0
Rotate data memory left through carry
The contents of the specified data memory and the carry flag are rotated 1 bit left. Bit 7 re-
