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 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.
