When TnBPOL = 1
TnCCLR = 1;
Mode Bits TnA(B)M1, TnA(B)M0 = 10
TnPW M1/TnPWM0 = 00
PWM Mode
- Edge Aligned
Note:
1. Here TnCCLR = 1 therefore CCRA clears counter and determines PWM period
2. Internal PWM function continues even when TnBIO1, TnBIO0 = 00 or 01
3. CCRA controls TPnB PWM period and CCRB controls TPnB PWM duty
