Hi Bill,
No, of course it isn't. But for a function as critical
as this, surely one would look at the assembly generated.
There will no doubt be need to adjust things a little bit.
It might end up being something more like:
while(1){
delay_us(4);
#asm
NOP
#endasm
output_toggle(PIN_A0);
}
On another note, there are PICs that have hardware divider
chains built in. The 12F629 is one of them.
