Number Conversion Instructions
BCD
The Binary Coded Decimal instruction
converts a binary value in the accumulator
to the equivalent BCD value. The result
resides in the accumulator.
In the following example, when X1 is on, the binary (HEX) value in V2000 and V2001
is 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.
Discrete Bit Flags Description
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP70 On anytime the value in the accumulator is negative.
