DECFSZ
Decrement f, Skip if 0

(f) - 1
(destination);
skip if result = 0
None
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 ‘
1
’, the next instruc-
tion is executed. If the result is ‘
0
’,
then a
NOP
is executed instead,
making it a 2T
CY
instruction.

None
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.
