ETM CCRB Compare Match Output Mode – TnCCLR=1
Note: 1. With TnCCLR=1, a Comparator A match will clear the counter
2. The TPnB output pin is controlled only by the TnBF flag
3. The TPnB output pin is reset to its initial state by a TnON bit rising edge
4. The TnPF flag is not generated when TnCCLR=1
5. n=3
