PORT: Port Control and Interrupts

Overview

The MCUXpresso SDK provides a driver for the Port Control and Interrupts (PORT) module of MCUXpresso SDK devices.

Typical configuration use case

Input PORT configuration

/* Input pin PORT configuration */
port_pin_config_t config = {
    kPORT_PullUp,
    kPORT_FastSlewRate,
    kPORT_PassiveFilterDisable,
    kPORT_OpenDrainDisable,
    kPORT_LowDriveStrength,
    kPORT_MuxAsGpio,
    kPORT_UnLockRegister,
};
/*  Sets the configuration */
PORT_SetPinConfig(PORTA, 4, &config);

I2C PORT Configuration

/*  I2C pin PORTconfiguration */
port_pin_config_t config = {
    kPORT_PullUp,
    kPORT_FastSlewRate,
    kPORT_PassiveFilterDisable,
    kPORT_OpenDrainEnable,
    kPORT_LowDriveStrength,
    kPORT_MuxAlt5,
    kPORT_UnLockRegister,
};
PORT_SetPinConfig(PORTE,24u,&config);
PORT_SetPinConfig(PORTE,25u,&config);
