Dead Zone Length Register 1.
Inserted data range: 255~0.
(Unit : One PWM clock cycle)
If DZL1=0, then Dead zone length = 0
Dead Zone Length Register 0.
Inserted data range: 255~0.
(Unit : One PWM clock cycle)
If DZL0=0, then Dead zone length = 0
Pre-scale register for Channel 2 & 3.
Pre-scale output clock frequency = PCLK / (pre-scale23 + 1)
If PPR=0, then the pre-scale output clock will be stopped.
Pre-scale register for Channel 0 & 1.
Pre-scale output clock frequency = PCLK / (pre-scale01 + 1)
If PPR=0, then the pre-scale output clock will be stopped.
