Multiply Literal with WREG
[ label ]

(k x WREG)
None
An unsigned multiplication is carried
out between the contents of WREG
and the 8-bit literal ’k’. The 16-bit
result is placed in PRODH:PRODL
register pair. PRODH contains the
high byte.
WREG is unchanged.
None of the status flags are affected.
Note that neither overflow, nor carry
is possible in this operation. A zero
result is possible, but not detected.

(WREG x f)
None
An unsigned multiplication is carried
out between the contents of WREG
and the register file location ’f’. The
16-bit result is stored in the
PRODH:PRODL register pair.
PRODH contains the high byte.
Both WREG and ’f’ are unchanged.
None of the status flags are affected.
Note that neither overflow, nor carry
is possible in this operation. A zero
result is possible, but not detected.
