1. Here TnCCLR=1 therefore CCRA clears the counter and determines the PWM period
2. The internal PWM function continues running even when TnBIO [1:0] = 00 or 01
3. The CCRA controls the TPnB PWM period and CCRB controls the TPnB PWM duty
4. Here the TM pin control register should not enable the TPnA pin as a TM output pin.
