The contents of register ’f’ is moved
to a destination dependent upon
the status of ’d’. If 'd' is 0, the result
is placed in WREG. If 'd' is 1, the
result is placed back in register 'f'
(default). Location 'f' can be any-
where in the 256 byte bank. 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).
