| * DADCX.A | Add carry decimally to destination address-word | ||
| * DADCX.[W] | Add carry decimally to destination word | ||
| * DADCX.B | Add carry decimally to destination byte | ||
| Syntax | DADCX.A dst | ||
| DADCX dst or DADCX.W dst | |||
| DADCX.B dst | |||
| Operation | dst + C → dst (decimally) | ||
| Emulation | DADDX.A #0,dst | ||
| DADDX #0,dst | |||
| DADDX.B #0,dst | |||
| Description | The carry bit (C) is added decimally to the destination. | ||
| Status Bits | N: | Set if MSB of result is 1 (address-word > 79999h, word > 7999h, byte > 79h), reset if MSB is 0 | |
| Z: | Set if result is zero, reset otherwise | ||
| C: | Set if the BCD result is too large (address-word > 99999h, word > 9999h, byte > 99h), reset otherwise | ||
| V: | Undefined | ||
| Mode Bits | OSCOFF, CPUOFF, and GIE are not affected. | ||
| Example | The 40-bit counter, pointed to by R12 and R13, is incremented decimally. | ||
DADDX.A #1,0(R12) ; Increment lower 20 bits
DADCX.A 0(R13) ; Add carry to upper 20 bits
