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 anywhere 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).
