The contents of register ‘f’ are
incremented. If ‘d’ is ‘0’, the result is
placed in W. If ‘d’ is ‘1’, the result is
placed back in register ‘f’ (default).
If the result is ‘0’, the next instruction
which is already fetched is discarded
and a NOP is executed instead, making
it a two-cycle instruction. 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).
