Vendor: Nordic Semiconductor

Description

nRFx S/W PWM

Properties

Properties not inherited from the base binding file.

Name

Type

Details

generator

phandle

Reference to TIMER or RTC instance for generating PWM output signals

This property is required.

channel-count

int

Number of PWM channels. Limited by RTC/TIMER instance compare registers
minus 1.

This property is required.

clock-prescaler

int

Clock prescaler for RTC or TIMER used for generating PWM output signals.

RTC: needs to be set to 0, which gives 32768 Hz base clock for PWM
generation.

TIMER: 16 MHz / 2^prescaler base clock is used for PWM generation.

This property is required.

#pwm-cells

int

Number of items to expect in a pwm specifier

This property is required.

Constant value: 1

Specifier cell names

  • pwm cells: channel
