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:
10
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.
Words:
1
Cycles:
2
Example
GOTO THERE
After Instruction
PC =
Address THERE
INCF
Increment f
Syntax:
[
label ]
INCF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f) + 1
→ (dest)
Status Affected:
Z
Encoding:
00
1010
dfff
ffff
Description:
The contents of register ’f’ are
incremented. 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’.
Words:
1
Cycles:
1
Example
INCF
CNT,
1
Before Instruction
CNT
=
0xFF
Z=
0
After Instruction
CNT
=
0x00
Z=
1
INCFSZ
Increment f, Skip if 0
Syntax:
[
label ]
INCFSZ f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f) + 1
→ (dest), skip if result = 0
Status Affected:
None
Encoding:
00
1111
dfff
ffff
Description:
The contents of register ’f’ are
incremented. 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.

0,
PC
=
address HERE +1
IORLW
Inclusive OR Literal with W
Syntax:
[
label ]
IORLW k
Operands:
0
≤ k ≤ 255
Operation:
(W) .OR. k
→ (W)
Status Affected:
Z
Encoding:
11
1000
kkkk
Description:
The contents of the W register are
OR’ed with the eight bit literal 'k'.
The result is placed in the W reg-
ister.
Words:
1
Cycles:
1
Example
IORLW
0x35
Before Instruction
W
=
0x9A
After Instruction
W=
0xBF
Z=
1
