MULLW
Multiply Literal with WREG
Syntax:
[
label ]
MULLW
k
Operands:
0
≤ k ≤ 255
Operation:
(k x WREG)
→ PRODH:PRODL
Status Affected:
None
Encoding:
1011
1100
kkkk
Description:
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 ags are affected.
Note that neither overow nor carry
is possible in this operation. A zero
result is possible but not detected.

ffff
Description:
An unsigned multiplication is carried
out between the contents of WREG
and the register le 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 ags are affected.
Note that neither overow nor carry
is possible in this operation. A zero
result is possible but not detected.
