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’.
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,
overriding the BSR value. If ‘a’ = 1, then
the bank will be selected as per the
BSR value.
