Q1
Multiply Literal with W
[ label ]
0
(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 the
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 opera-
tion. 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 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’ = 1, then the bank will be
selected as per the BSR value
(default).
