Note: 1. Here TnCCLR=1 therefore CCRA clears the counter and determines the PWM period
2. TnPWM [1:0]=11 therefore the PWM is centre aligned
3. The internal PWM function continues running even when TnBIO [1:0]=00 or 01
4. CCRA controls the TPnB PWM period and CCRB controls the TPnB PWM duty
5. CCRP will generate an interrupt request when the counter decrements to its zero value
