None
GOTO allows an unconditional branch
anywhere within the entire
2-Mbyte memory range. The 20-bit
value ‘k’ is loaded into PC<20:1>. GOTO
is always a two-cycle instruction.

(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 is selected.
If ‘a’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a’ is ‘0’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f

Bit-Oriented Instructions in Indexed
Literal Offset Mode” for details.
