NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V1400 will be loaded into the accumulator
using the Load instruction. The binary value in V1420 is multiplied by the binary value in the
accumulator using the Multiply Binary instruction. The value in the accumulator is copied to
V1500 using the Out instruction.

Multiply Binary (MULB)
Multiply Binary is a 16-bit instruction that multiplies the
binary value (Aaaa), which is either a V-memory location or
a 4-digit (max.) binary constant, by the binary value in the
accumulator. The result can be up to 32 bits and resides in the
accumulator.
