The contents of register ’f’ are
decremented. 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, the next instruc-
tion, which is already fetched, is
discarded. A NOP is executed
instead making it a two-cycle
instruction.

GOTO is an unconditional branch.
The eleven-bit immediate value is
loaded into PC bits <10:0>. The
upper bits of PC are loaded from
PCLATH<4:3>. GOTO is a two-
cycle instruction.
