SWM: Switch Matrix Module

Overview

The MCUXpresso SDK provides a peripheral driver for the Switch Matrix Module (SWM) module of MCUXpresso SDK devices.

SWM: Switch Matrix Module

SWM Operations

The function SWM_SetMovablePinSelect() will selects a movable pin designated by its GPIO port and bit numbers to a function.

The function SWM_SetFixedMovablePinSelect() will selects a fixed movable pin designated by its GPIO port and bit numbers to a function.

The function SWM_SetFixedPinSelect() will enables a fixed-pin function in PINENABLE0 or PINENABLE1.
