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.
NOTE: Status flags are valid only until another instruction uses the same flag.

Shift Left (SHFL)
Shift Left is a 32-bit instruction that shifts the bits in the
accumulator a specified number (Aaaa) of places to the left.
The vacant positions are filled with zeros and the bits shifted
out of the accumulator are discarded.
