Multiply (MUL)
Multiply is a 16-bit instruction that multiplies the BCD
value (Aaaa), which is either a V-memory location or a
4–digit (max.) constant, by the BCD value in the lower 16
bits of the accumulator The result can be up to 8 digits and
resides in the accumulator.
NOTE: The status flags are only valid until another instruction that uses the same flags is executed.
In the following example, when X1 is on, the value in V2000 will be loaded into the
accumulator using the Load instruction. The value in V2006 is multiplied by the value in the
accumulator. The 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.
SP75 On when a BCD instruction is executed and a NON-BCD number was encountered.
