literal ’k’
Multiply Literal with WREG
[ label ]
0
(WREG) x k
None
An unsigned multiplication is car-
ried 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 opera-
tion. A zero result is possible but
not detected.

(WREG) x (f)
None
An unsigned multiplication is car-
ried out between the contents of
WREG and the register file loca-
tion ’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 opera-
tion. A zero result is possible but
not detected. If ’a’ is 0, the
Access Bank will be selected,
overriding the BSR value. If ’a’ is
1, the Bank will be selected as
per the BSR value.
