GPIO_PinConfig power mode configuration macros
For devices that support low power modes, standard GPIO interrupts may be disabled in some modes. These defines allow configuring individual pins as wake-up sources. The GPIO module's wake up configuration is always enabled if it exists, so there is no module-level configuration. See the device-specific header files for details.
#define	GPIO_CFG_SHUTDOWN_WAKE_OFF
#define	GPIO_CFG_SHUTDOWN_WAKE_HIGH
#define	GPIO_CFG_SHUTDOWN_WAKE_LOW

GPIO_pinconfig macro preventing configuration
Should be used if a pin is configured before the first GPIO_init() call, and should not be overwritten
#define	GPIO_CFG_DO_NOT_CONFIG

GPIO_Mux configuration macros
For additional muxing options, see the directions in the device-specific GPIO driver.
#define	GPIO_MUX_GPIO
