INV
The Invert instruction inverts or takes the
one’s complement of the 32 bit value in the
accumulator. The result resides in the
accumulator.
In the following example, when X1 is on, the value in V2000 and V2001 will be loaded
into the accumulator using the Load Double instruction. The value in the
accumulator is inverted using the Invert instruction. The value in the accumulator is
copied to V2010 and V2011 using the Out Double instruction.
