Enable driver to utilize PWM on the Nordic Semiconductor nRF5x series.

When used with HF timer it provides up to 3 pins, utilizing two PPI channels per pin and one GPIOTE config per pin.

When used with RTC it provides up to 3 pins, utilizing three PPI channels per pin and one GPIOTE config per pin.

Direct dependencies¶

SOC_FAMILY_NRF && PWM

(Includes any dependencies from ifs and menus.)

Default¶

y if !PWM_NRFX
