Details

divider-int-0

int

The integral part of the divider for pwm slice 0.
If a value between 1 and 255 is set, it will be set to the register
as the integer part of the divider.
If the value is set to 0 or this property is not defined when setting
the number of cycles to PWM, a division ratio appropriate to that value is set.

divider-frac-0

int

The fractional part of the divider for pwm slice 0.
This number should be in the range 0 - 15.
When the "divider-int-0" is set to 0 or is not defined, this property will be
ignored.
