Data Structures
struct	gpio_hwreg_t
	GPIO hardware register map. More...
struct	gpio_instance_t

Functions
void	gpio_applyConfig (gpio_instance_t *inst)
	Apply stored GPIO configuration to hardware.
GPIO (Get Functions)
Read values from the GPIO hardware registers.
u32	gpio_getInput (gpio_instance_t *inst)
	Read GPIO Input Register.
u32	gpio_getOutput (gpio_instance_t *inst)
	Get stored GPIO Output Value.
u32	gpio_getOutputEnable (gpio_instance_t *inst)
	Get stored GPIO Output Enable Mask.
u32	gpio_getInterruptRiseEnable (gpio_instance_t *inst)
	Get Rising Edge Interrupt Mask.
u32	gpio_getInterruptFallEnable (gpio_instance_t *inst)
	Get Falling Edge Interrupt Mask.
u32	gpio_getInterruptHighEnable (gpio_instance_t *inst)
	Get High Level Interrupt Mask.
u32	gpio_getInterruptLowEnable (gpio_instance_t *inst)
	Get Low Level Interrupt Mask.
GPIO (Set Functions)
Write values to the GPIO registers. Note Call gpio_applyConfig() to make these changes effective.
void	gpio_setOutput (gpio_instance_t *inst, u32 value)
	Set GPIO Output Value.
void	gpio_setOutputEnable (gpio_instance_t *inst, u32 value)
	Set GPIO Output Enable (Direction).

	Set Rising Edge Interrupt Enable.
void	gpio_setInterruptFallEnable (gpio_instance_t *inst, u32 value)
	Set Falling Edge Interrupt Enable.
void	gpio_setInterruptHighEnable (gpio_instance_t *inst, u32 value)
	Set High Level Interrupt Enable.
void	gpio_setInterruptLowEnable (gpio_instance_t *inst, u32 value)
	Set Low Level Interrupt Enable.
