Binary Coded Decimal (BCD)
The Binary Coded Decimal instruction converts a binary value
230
in the accumulator to the equivalent BCD value. The result
240
resides in the accumulator.
250-1
In the following example, when X1 is on, the binary (HEX) value in V2000 and V2001 is
260
loaded into the accumulator using the Load Double instruction. The binary value in the
accumulator is converted to the BCD equivalent value using the BCD instruction. The BCD
value in the accumulator is copied to V2010 and V2011 using the Out Double instruction.
