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 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 1, the next instruction is
executed. If the result is 0, a NOP is
executed instead making it a 2TCY
instruction
