INPUTMUX: Input Multiplexing Driver

Overview

The MCUXpresso SDK provides a driver for the Input multiplexing (INPUTMUX).
It configures the inputs to the pin interrupt block, DMA trigger, and frequency measure function. Once configured, the clock is not needed for the inputmux.

Input Multiplexing Driver operation

INPUTMUX_AttachSignal function configures the specified input

Typical use case

Refer to the driver examples codes located at <SDK_ROOT>/boards/<BOARD>/driver_examples/inputmux
