* To test PWM, use the PCNT to calculateit to judge it work right or not.
* e.g: judge the start and stop.
* If started right, the PCNT will count the pulse.
* If stopped right, the PCNT will count no pulse.
*
*
* test environment UT_T1_MCPWM:
* 1. connect GPIO4 to GPIO5
* 2. connect GPIO13 to GPIO12
* 3. connect GPIO27 to GPIO14
*
* all of case separate different timer to test in case that one case cost too much time
