Vendor: Nordic Semiconductor

Description

nRFx S/W PWM

Properties

Node specific properties

Base properties

Properties not inherited from the base binding file.

Name	Type	Details
timer-instance	int	Timer instance to use for generating the PWM output signals This property is required.
channel-count	int	Number of PWM channels. Limited by timer instance compare registers minus 1. This property is required.
clock-prescaler	int	Clock prescaler for timer used for generating the PWM output signals with frequency = 16 MHz / 2^prescaler This property is required.
ppi-base	int	PPI base used for PPI index calculation used for PWM output generation This property is required.
gpiote-base	int	GPIOTE base used for GPIOTE index calculation used for PWM output generation This property is required.
#pwm-cells	int	Number of items to expect in a pwm specifier This property is required. Constant value: 1

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-sw-pwm” compatible.
