f → dest
N, Z
The contents of register 'f' are
moved to a destination dependent
upon the status of ‘d’. If 'd' is 0, the
result is placed in W. 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).
