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
instruction, 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 immedi-
ate 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.
