5.4.3
RCR (FNC 32)
Operation:
The bit pattern of the destination device (D)is rotated
n bit places to the right on every operation of the
instruction.
The status of the last bit rotated is moved into the
carry flag M8022. On the following operation of the
instruction M8022 is the first bit to be moved back
into the destination device.
The example shown left is based on the instruction
noted above it, where the bit pattern represents the
contents of D0.
n bit places to the right on every operation of the
instruction.
The status of the last bit rotated is moved into the
carry flag M8022. On the following operation of the
instruction M8022 is the first bit to be moved back
into the destination device.
The example shown left is based on the instruction
noted above it, where the bit pattern represents the
contents of D0.
