DECFSZ
Decrement f, Skip if 0
Syntax:
[
label ] DECFSZ f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f) - 1
→ (dest);
skip if result = 0
Status Affected:
None
Encoding:
00
1011
dfff
ffff
Description:
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 reg-
ister ’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
Unconditional Branch
Syntax:
[
label ]
GOTO k
Operands:
0
≤ k ≤ 2047
Operation:
k
→ PC<10:0>
PCLATH<4:3>
→ PC<12:11>
Status Affected:
None
Encoding:

1kkk
kkkk
Description:
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.

INCF
Increment f
Syntax:
[
label ]
INCF f,d
Operands:

≤ f ≤ 127
d
∈ [0,1]
Operation:
