* DADC[.W] Add carry decimally to destination
* DADC.B Add carry decimally to destination
Syntax DADC
DADC.B
Operation dst + C −> dst (decimally)
Emulation DADD
DADD.B
Description The carry bit (C) is added decimally to the destination.
Status Bits N: Set if MSB is 1
Z: Set if dst is 0, reset otherwise
C: Set if destination increments from 9999 to 0000, reset otherwise
V: Undefined
Mode Bits OSCOFF, CPUOFF, and GIE are not affected.
Example The four-digit decimal number contained in R5 is added to an eight-digit deci-
mal number pointed to by R8.
