Thanks for the help

It seems I’m barking up the wrong tree then as I don't want to use an external clock source, and i can’t interrupt the program or pause it.


Is it possible simply to increment a variable every execution cycle?

i.e.

tick var byte
tick_flag var byte


start:

If tick > 99 then

Tick = 0
tick_flag = 1

Else

tick = tick + 1

End if

Goto start ‘ loop

But how can I approximate this to a time scale I can use. The datasheet state the execution cycle time as 1uS , forgive my ignorance but does that mean the above code will increment every 1uS ?
