(3) Rotation:
There are two kinds of rotation operation, one is rotation left, the other is rotation right.
RLCA instruction rotates Acc value to left, shift the CF value into the LSB bit of Acc and the shift out data
will be hold in CF.
RRCA instruction operation rotates Acc value to right, shift the CF value into the MSB bit of Acc and the
shift out data will be hold in CF.
PROGRAM EXAMPLE: To rotate Acc right and shift a "1" into the MSB bit of Acc .
TTCFS; CF
← 1
RRCA; rotate Acc right and shift CF=1 into MSB.
