Arithmetic // RRC, RR (Rotate Right Circular, Rotate Right)
0xFDCB**19
- u64971
The contents of the memory location pointed to by iy plus * are rotated right one bit position. The contents of bit 0 are copied to the carry flag and the previous contents of the carry flag are copied to bit 7. The result is then stored in c.
