Interrupting the interrupt

[tmoulder]

Greetings!

I'm planning to use the 1.25mS interrupt and the HSC with Reload interupt in the same program. My question is this:

If the 1.25mS interrupt routine is in progress, and my HSC reaches target value during this interlude, what happens? Will the timed interrupt be interrupted?

Thanks,

TM

HSC Reload Interrupt is with higher priority. If it will come during execution of 1.25 ms, it will interrupt it.

Please note, that usual time of execution of interrupt needs to be in range of several microseconds to few tens microseconds...
