INCF
Increment f
Syntax INCF f, d
0 ≤ f ≤ FFh
d ∈ [0,1]
Operation
[Destination] ← [f] +1
Flag Affected Z
Description [f] is incremented. If d is 0, the result is stored in the W register. If d is 1, the result is
stored back in [f].
Cycle 1
Example 1:
INCF OPERAND,0
Before instruction:
W = 88h, OPERAND = 23h
After instruction:
W = 24h, OPERAND = 23h
Example 2:
INCF OPERAND,1
Before instruction:
W = 88h, OPERAND = 23h
After instruction:
W = 88h, OPERAND = 24h
INCFSZ
Increment f, skip if zero
Syntax INCFSZ f, d
0 ≤ f ≤ FFh
d ∈ [0,1]
Operation
[Destination] ← [f] + 1, skip if the result is zero
Flag Affected None
Description [f] is incremented. If d is 0, the result is stored in the W register. If d is 1, the result is
stored back in [f].
If the result is 0, then the next fetched instruction is discarded and a NOP is
executed instead making it a two-cycle instruction.
Cycle 1, 2
Example:
Node INCFSZ FLAG,
1
OP1 :
OP2 :
Before instruction:
PC = address (Node)
After instruction:
[FLAG] = [FLAG] + 1
If [FLAG] = 0
PC = address(OP2)
If [FLAG] ≠ 0
PC = address(OP1)
IORLW
Inclusive OR literal with W
Syntax IORLW k
0 ≤ k ≤ FFh
Operation
[W] ← [W] | k
Flag Affected Z
Description Inclusive OR the content of the W register and the eight-bit literal “k”. The result is
stored in the W register.
Cycle 1
Example:
IORLW 85h
Before instruction:
W = 69h
After instruction:
W = Edh
