|
Reference to TIMER or RTC instance for generating PWM output signals
This property is required. |
|
|
Number of PWM channels. Limited by RTC/TIMER instance compare registers
minus 1.
This property is required. |
|
|
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. |
|
|
Number of items to expect in a pwm specifier
This property is required. Constant value: |
Deprecated properties not inherited from the base binding file.
(None)
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.

|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
