1. Shift to the right with carry loop RCR/RCRD

1.1. Instruction Description#

The instruction moves the value of a single character (IN1) to the right (IN2) bits and loads the result into the single character (OUT). At the beginning of the movement, place the carry flag on the right side, and after the movement is completed, write the move out bit into the carry flag.

Related registers	Description
M8165	Direction indication for bit movement command. (OFF: Move to the right, ON: Move to the left)
M8166	The last bit to be removed.
M8167	The result of the shift operation is 0.
