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’.

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 instruc-
tion.

IORLW k
Operands:
0
≤ k ≤ 255
Operation:
(W) .OR. (k)
→ (W)
Status Affected:

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.
