literal ‘k’
Multiply Literal with W

(W) x k
None
An unsigned multiplication is
carried out between the contents
of W and the 8-bit literal ‘k’. The
16-bit result is placed in
PRODH:PRODL register pair.
PRODH contains the high byte.
W 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.

(W) x (f)
None
An unsigned multiplication is
carried out between the contents
of W and the register file location
‘f’. The 16-bit result is stored in
the PRODH:PRODL register
pair. PRODH contains the high
byte.
Both W 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. If ‘a’ is
‘0’, the Access Bank will be
selected, overriding the BSR
value. If ‘a’ = 1, then the bank
will be selected as per the BSR
value (default).
