DESCRIPTIONS
[31:24]
DZI1
DZI1: Dead zone interval register 1, these 8-bit determine dead zone
length.
The 1 unit time of dead zone length is received from clock selector 2.
[23:16]
DZI0
DZI0: Dead zone interval register 0, these 8-bit determine dead zone
length.
The 1 unit time of dead zone length is received from clock selector 0.
[15:8]
CP1
CP1 : Clock prescaler 1 for PWM Timer channel 2 & 3
Clock input is divided by (CP1 + 1) before it is fed to the counter. 2 & 3
If CP1=0, then the prescaler 1 output clock will be stopped.
[7:0]
CP0
CP0 : Clock prescaler 0 for PWM Timer channel 0 & 1
Clock input is divided by (CP0 + 1) before it is fed to the counter. 0 & 1
If CP0=0, then the prescaler 0 output clock will be stopped.
