Dead zone interval register for pair of channel2 and channel3 (PWM2 and
PWM3 pair for PWM group A, PWM6 and PWM7 pair for PWM group B)
These 8 bits determine dead zone length.
The unit time of dead zone length is received from corresponding CSR bits.
Dead zone interval register for pair of channel 0 and channel 1 (PWM0 and
PWM1 pair for PWM group A, PWM4 and PWM5 pair for PWM group B)
These 8 bits determine dead zone length.
The unit time of dead zone length is received from corresponding CSR bits.
Clock prescaler 2 (PWM counter 2 & 3 for group A and PWM counter 6 & 7 for
group B)
Clock input is divided by (CP23 + 1) before it is fed to the corresponding PWM
counter
If CP23=0, then the clock prescaler 2 output clock will be stopped. So corresponding
