Applied Instructions 5
5-35
5.4.1
ROR (FNC 30)
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 copied to the carry
flag M8022.
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 copied to the carry
flag M8022.
The example shown left is based on the instruction
noted above it, where the bit pattern represents the
contents of D0.
5.4.2
ROL (FNC 31)
Operation:
The bit pattern of the destination device (D) is rotated
n bit places to the left on every operation of the
instruction.
The status of the last bit rotated is copied to the carry
flag M8022.
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 left on every operation of the
instruction.
The status of the last bit rotated is copied to the carry
flag M8022.
