RRC —
RRC
Operation:
Description:
Example:
Rotate Accumulator Right through Carry
A
The four bits in the accumulator and the carry flag are together rotated one bit to the right. Bit 0
moves into the carry flag and the original carry value moves into the bit 3 accumulator position.
The accumulator contains the value 5H (0101B) and the carry flag is cleared to logic zero. The
instruction
RRC
leaves the accumulator with the value 2H (0010B) and the carry flag set to logic one.
