Functions
Configuration
static void	PORT_SetPinConfig (PORT_Type *base, uint32_t pin, const port_pin_config_t *config)
	Sets the port PCR register.
static void	PORT_SetMultiplePinsConfig (PORT_Type *base, uint32_t mask, const port_pin_config_t *config)
	Sets the port PCR register for multiple pins.
static void	PORT_SetMultipleInterruptPinsConfig (PORT_Type *base, uint32_t mask, port_interrupt_t config)
	Sets the port interrupt configuration in PCR register for multiple pins.
static void	PORT_SetPinMux (PORT_Type *base, uint32_t pin, port_mux_t mux)
	Configures the pin muxing.
static void	PORT_EnablePinsDigitalFilter (PORT_Type *base, uint32_t mask, bool enable)
	Enables the digital filter in one port, each bit of the 32-bit register represents one pin.

Interrupt
static void	PORT_SetPinInterruptConfig (PORT_Type *base, uint32_t pin, port_interrupt_t config)
	Configures the port pin interrupt/DMA request.
static void	PORT_SetPinDriveStrength (PORT_Type *base, uint32_t pin, uint8_t strength)
	Configures the port pin drive strength.
static uint32_t	PORT_GetPinsInterruptFlags (PORT_Type *base)
	Reads the whole port status flag.
static void	PORT_ClearPinsInterruptFlags (PORT_Type *base, uint32_t mask)
	Clears the multiple pin interrupt status flag.
