(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.

(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.
