GOTO allows an unconditional branch
anywhere within entire 2-Mbyte memory
range. The 20-bit value ‘k’ is loaded into
PC<20:1>. GOTO is always a two-cycle
instruction.

register ‘f’

(f) + 1
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 ‘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).
