The accumulator contents and the program memory contents specified with the control register P13 and
register pair R
If H is specified, b
The accumulator contents and the immediate data are exclusive-ORed and the results are entered in
the accumulator.
The accumulator contents are incremented (+1).
The accumulator contents are rotated anticlockwise bit by bit.
The accumulator contents are rotated anticlockwise bit by bit.
If A = 0H at the time of command execution, an internal reset takes effect.
