Hi,
I reported a bug on the 18th & was asked to test some different code to isolate the problem .
I ran the code & reported back on the 19th .
I've sent 3 emails now & had no response ?

Hi,
The timer Problem has become worse with SDKv1.1.0
My original problem was the us Timer was stopping and restarting with long time periods between each stop or start .
Now the problem is resulting in wdt resets .

I have done further tests on the problem using my scope.
I toggle a pin on each timer event.
I have been triggering on pulses less than 10uS with the uS Timer setup at 100uS .

This is the results .
1/ 100uS pulses stop for 5.4 milli Secs
2/ 200uS of 4uS pulses
3/ 60uS of mark or space
4/ normal 100uS pulses resume

Here is the code .
