Bits
Description
[31:24]
DTCNT23
Dead Zone Interval Register for Pair of PWM0CH2 and PWM0CH3
These 8 bits determine dead zone length.
The unit time of dead zone length is that from clock selector 0.
[23:16]
DTCNT01
Dead Zone Interval Register for Pair of PWM0CH0 and PWM0CH1
These 8 bits determine dead zone length.
The unit time of dead zone length is that from clock selector 0.
[15:8]
CLKPSC23
Clock Pre-scaler for Pair of PWM0CH2 and PWM0CH3
Clock input is divided by (CL 1)
If CLKPSC23 = 0, then the pre-scaler output clock will be stopped.
This implies PWM counter 2 and 3 will also be stopped.
[7:0]
CLKPSC01
Clock Pre-scaler Pair of PWM0CH0 and PWM0CH1
Clock input is divided by (CL 1)
If CLKPSC01 = 0, then the pre-scaler output clock will be stopped.
This implies PWM counter 0 and 1 will also be stopped.
