Hi @xiangjun_rong,
Using MASK Register, solve a problem put not all. During the begining of code, the pin float and I get problem, after configuration using mask all work fine. I only release mask after calibration of sensor, so, I set mask to normal again, and start pwm.
I put my main code above. From begining of main until last line from example, the pin is floating, shorting the PS, is not so much time but I don't know if this going to be a problem.
