From d21382ba4edc2f6fe4dbfcfac3f23e989b724364 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20Stasiak?= Date: Tue, 7 Jan 2025 14:51:23 +0100 Subject: [PATCH] [nrf fromlist] drivers: pwm: nrfx: Add idle output to PWM driver. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fast PWM120 prevents GPIO from driving pin with low/high state when PWM duty is 0% or 100%. Idleout feature needs to be used. It can be configured when PWM is disabled and works while it is enabled.
