Dead zone interval
6.20.4 PWM Timer Start procedure
1. Setup clock selector (PWM_CSR)
2. Setup prescaler & dead zone interval (PWM_PPR)
3. Setup inverter on/off, dead zone generator on/off, toggle mode /one-shot mode, and PWM timer
off. (PWM_PCR)
4. Setup comparator register (PWM_CMR)
5. Setup counter register (PWM_CNR)
6. Setup interrupt enable register (PWM_PIER)
7. Enable PWM timer (PWM_PCR)
6.20.5 PWM Timer Stop procedure
Method 1 : Set 16-bit down counter(PWM_CNR) as 0, and monitor PWM_PDR. When PWM_PDR
reaches to 0, disable PWM timer (PWM_PCR). (Recommended)
Method 2 : Set 16-bit down counter(PWM_CNR) as 0. When interrupt request happen, disable PWM
timer (PWM_PCR). (Recommended)
Method 3 : Disable PWM timer directly (PWM_PCR). (Not recommended)
