00
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
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.
