If Skip:
Increment f, Skip if 0
[ label ]
0
d
(f) + 1
None
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 2T
instruction
