The double buffering function allows CMRx written at any point in current cycle. The loaded value
will take effect from next cycle.
PWM controller is implemented with Dead Zone generator. They are built for power device
protection. This function generates a programmable time gap to delay PWM rising output. User
can program PPRx.DZI to determine the Dead Zone interval.
