.

NOTE: No restrictions are placed on the sizes of input or output variables. If the
inputs differ in size (for example, an 8-bit byte compared with a 16-bit word),
then the smaller input is bit-extended with zeros to match the size of the larger
input.

Furthermore, if the result is larger than the output variable (for example, a 16-bit
result to be placed in an 8-bit output variable), then the high-order bits of the
result are discarded and the low-order bits are placed in the output.
