Section 3-11
Description
+BC(406) adds BCD values in Au, Ad, and CY and outputs the result to R.
Flags
Precautions
If Au or Ad is not BCD, an error is generated and the Error Flag will turn ON.
If as a result of the addition, the content of R is 0000 hex, the Equals Flag will
turn ON.
If an addition results in a carry, the Carry Flag will turn ON.
Note To clear the Carry Flay (CY), execute the Clear Carry (CLC(041)) instruction.
Examples
When CIO 000000 is ON in the following example, D00100, D00110, and CY
will be added as 4-digit BCD values, and the result will be output to D00120.
Indirect DM/EM
addresses in binary
@ D00000 to @ D32767
@ E00000 to @ E32767
