Got anything more definitive to go on? I've bee searching hardware timer, T4
timer, etc and all I seem to be able to find are comments like "yeah you can do
that" without the actual solution. If this is a FAQ, where is the FAQA
(Frequently Asked Question Answer), or ATFAQ (not related to AFLAC). Source
code would be useful. I've tried the T4timer.c code sample but what I'm seeing
is the timeout if-then lines overshooting the desired time by huge amounts.
