literal ‘k’
Multiply Literal with W
[ label ]
0 ≤ k ≤ 255
(W) x k → PRODH:PRODL
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.

register ‘f’
Multiply W with f
[ label ]
0 ≤ f ≤ 255
a ∈ [0,1]
(W) x (f) → PRODH:PRODL
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).
