| ADDC[.W] | Add source word and carry to destination word | |
| ADDC.B | Add source byte and carry to destination byte | |
| Syntax | ADDC src,dst or ADDC.W src,dst | |
| ADDC.B src,dst | ||
| Operation | src + dst + C → dst | |
| Description | The source operand and the carry bit C are added to the destination operand. The previous content of the destination is lost. | |
| Status Bits | N: | Set if result is negative (MSB = 1), reset if positive (MSB = 0) |
| Z: | Set if result is zero, reset otherwise | |
| C: | Set if there is a carry from the MSB of the result, reset otherwise | |
| V: | Set if the result of 2 positive operands is negative, or if the result of 2 negative numbers is positive, reset otherwise | |
| Mode Bits | OSCOFF, CPUOFF, and GIE are not affected. | |
| Example | Constant value 15 and the carry of the previous instruction are added to the 16-bit counter CNTR located in lower 64 K. | |
ADDC.W #15,&CNTR ; Add 15 + C to 16-bit CNTR
| Example | A table word pointed to by R5 (20-bit address) and the carry C are added to R6. The jump to label TONI is performed on a carry. R6.19:16 = 0 | |
ADDC.W @R5,R6 ; Add table word + C to R6
JC TONI ; Jump if carry
... ; No carry
| Example | A table byte pointed to by R5 (20-bit address) and the carry bit C are added to R6. The jump to label TONI is performed if no carry occurs. The table pointer is auto-incremented by 1. R6.19:8 = 0 | |
ADDC.B @R5+,R6 ; Add table byte + C to R6. R5 + 1
JNC TONI ; Jump if no carry
... ; Carry occurred
