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’. 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.
