Description:
The eight bit literal ’k’ is loaded into
WREG.
Description:
Move data from WREG to register
’f’. Location ’f’ can be anywhere in
the 256 byte bank. If ’a’ is 0, the
Access Bank will be selected, over-
riding the BSR value. If ’a’ = 1,
then the bank will be selected as
per the BSR value (default).
