Detailed Description

Fast GPIO register definition struct.

Definition at line 46 of file periph_cpu.h.

#include <periph_cpu.h>

Data Fields
__IO uint32_t	DIR
	Direction: Output if corresponding bit is set, otherwise input.

uint32_t	_reserved [3]
	12 bytes of reserved memory we don't need to access

__IO uint32_t	MASK
	Set bits to ignore corresponding bits when accessing `PIN`, `SET` or `CLR` register of this port.

__IO uint32_t	PIN
	The current state of each pin of this port is accessible here (regardless of direction): If bit is set input is high.

__IO uint32_t	SET
	Output pins are set to high by setting the corresponding bit.

__IO uint32_t	CLR
	Output pins are set to low by setting the corresponding bit.
