Status<6:5>
GOTO is an unconditional branch.
The 9-bit immediate value is
loaded into PC bits <8:0>. The
upper bits of PC are loaded from
Status<6:5>. GOTO is a two-cycle
instruction.

The contents of register ‘f’ are
incremented. If ‘d’ is ‘0’, the result
is placed in the W register. If ‘d’ is
‘1’, the result is placed back in
register ‘f’.

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