4.6.2.41 RRC
| RRC[.W] | Rotate right through carry destination word | ||
| RRC.B | Rotate right through carry destination byte | ||
| Syntax | RRC dst or RRC.W dst | ||
| RRC.B dst | |||
| Operation | C → MSB → MSB–1 → ... LSB+1 → LSB → C | ||
| Description | The destination operand is shifted right by 1 bit position as shown in Figure 4-41. The carry bit C is shifted into the MSB and the LSB is shifted into the carry bit C. | ||
| Status Bits | N: | Set if result is negative (MSB = 1), reset otherwise (MSB = 0) | |
| Z: | Set if result is zero, reset otherwise | ||
| C: | Loaded from the LSB | ||
| V: | Reset | ||
| Mode Bits | OSCOFF, CPUOFF, and GIE are not affected. | ||
| Example | RAM word EDE is shifted right 1 bit position. The MSB is loaded with 1. | ||
SETC ; Prepare carry for MSB
RRC EDE ; EDE = EDE >> 1 + 8000h
