Rotate and clear Assignment Help

Assignment Help: >> Logical - Rotate and clear

Rotate and clear:


These instructions rotate bits in a byte. The rotation may be left or right, and it is done one bit each of instruction. An instance might be where the accumulator has 11000011b in it. If we rotate left, the result shall be 10000111b. You can see that bit 7 has been now moved into bit 0 and all the other bits have move 1 bit position in, the left direction.


This instruction clears, or zero's out the accumulator. It is the same as moving a 0 into the accumulator. It also clears the C flag and sets the Z flag.
