Description

General Purpose Input/Output (GPIO) API.

This module contains functions to control the GPIO peripheral of Silicon Labs 32-bit MCUs and SoCs. The GPIO peripheral is used for pin configuration and direct pin manipulation and sensing as well as routing for peripheral pin connections.

Functions
void	GPIO_DbgLocationSet (unsigned int location)
	Sets the pin location of the debug pins (Serial Wire interface).

void	GPIO_DriveModeSet ( GPIO_Port_TypeDef port, GPIO_DriveMode_TypeDef mode)
	Sets drive mode for a GPIO port.

void	GPIO_ExtIntConfig ( GPIO_Port_TypeDef port, unsigned int pin, unsigned int intNo, bool risingEdge, bool fallingEdge, bool enable)
	Configure the GPIO external pin interrupt.

void	GPIO_PinModeSet ( GPIO_Port_TypeDef port, unsigned int pin, GPIO_Mode_TypeDef mode, unsigned int out)
	Set the mode for a GPIO pin.

GPIO_Mode_TypeDef	GPIO_PinModeGet ( GPIO_Port_TypeDef port, unsigned int pin)
	Get the mode for a GPIO pin.

	Clear one or more pending GPIO interrupts.

void	GPIO_IntDisable (uint32_t flags)
	Disable one or more GPIO interrupts.

void	GPIO_IntEnable (uint32_t flags)
	Enable one or more GPIO interrupts.

uint32_t	GPIO_IntGet (void)
	Get pending GPIO interrupts.

uint32_t	GPIO_IntGetEnabled (void)
	Get enabled and pending GPIO interrupt flags.

void	GPIO_IntSet (uint32_t flags)
	Set one or more pending GPIO interrupts from SW.

void	GPIO_Lock (void)
	Locks the GPIO configuration.

unsigned int	GPIO_PinInGet ( GPIO_Port_TypeDef port, unsigned int pin)
