INCF
Increment f
Syntax:
[ label ] INCF f,d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(f) + 1 → (dest)
Status Affected: Z
Encoding:
0010 10df ffff
Description:
The contents of register 'f' are incre-
mented. If 'd' is 0 the result is placed in
the W register. If 'd' is 1 the result is
placed back in register 'f'.

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 ≤ 31
d ∈ [0,1]
Operation:
(f) + 1 → (dest), skip if result = 0
Status Affected: None
Encoding:
0011 11df ffff
Description:
The contents of register 'f' are incre-
mented. 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, then the next instruc-
tion, which is already fetched, is dis-
carded and an NOP is executed instead
making it a two cycle instruction.

IORLW
Inclusive OR literal with W
Syntax:
[ label ] IORLW k
Operands:
0 ≤ k ≤ 255
Operation:
(W) .OR. (k) → (W)
Status Affected: Z
Encoding:
1101 kkkk kkkk
Description:
The contents of the W register are
OR’ed with the eight bit literal 'k'. The
result is placed in the W register.

Example:
IORLW 0x35
Before Instruction
W = 0x9A
After Instruction
W = 0xBF
Z=0
IORWF
Inclusive OR W with f
Syntax:
[ label ] IORWF f,d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(W).OR. (f) → (dest)
Status Affected: Z
Encoding:
0001 00df ffff
Description:
Inclusive OR the W register with regis-
ter 'f'. If 'd' is 0 the result is placed in
the W register. If 'd' is 1 the result is
placed back in register 'f'.
