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.
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 bit pattern in the
accumulator is shifted 2 bits to the left using the Shift Left instruction. The value in the
accumulator is copied to V2010 and V2011 using the Out Double instruction.
