2.19 BCD CONVERSION Instruction (BCD)

[Outline]

The BCD instruction converts a binary value in the Source into a BCD value (BCD conversion) and

the result is stored in the Dest. If the 4 - digit decimal value in the Source is abcd, the output value

(Dest) of the BCD instruction can be determined by the following formula:

Dest = (a × 4096) + (b × 256) + (c × 16) + d

Although the above formula is applicable even if the value in the Source cannot be expressed in BCD

notation (e.g. numbers greater than 9999 or negative numbers), correct results are obtained in such

cases.
