5.4.3 RCR (FNC 32)
Operation:
The bit pattern of the destination device (D)is rotated
n bit places to the ri
g
ht on ever
y
operation of the
instruction.
The status of the last bit rotated is moved into the
carr
y
fla
g
M8022. On the followin
g
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.
5.4.4 RCL (FNC 33)
Operation:
The bit pattern of the destination device (D)is rotated
n bit places to the left on ever
y
operation of the
instruction.
The status of the last bit rotated is moved into the
carr
y
fla
g
M8022. On the followin
g
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.
