Rotate Left (ROTL)
Rotate Left is a 32-bit instruction that rotates the bits in the
accumulator a specified number (Aaaa) of places to the left.
In the following example, when X1 is on, the value in V1400 and V1401 will be loaded into
the accumulator using the Load Double instruction. The bit pattern in the accumulator is
rotated 2 bit positions to the left using the Rotate Left instruction. The value in the
accumulator is copied to V1500 and V1501 using the Out Double instruction.
