宏定义说明

hal_gpio_read_bit

#define hal_gpio_read_bit	(		x,
			y
	)		(((uint32_t)(x) >> (uint32_t)(y)) & 1U)

Read bit y in x

hal_gpio_set_bit

#define hal_gpio_set_bit	(		x,
			y,
			z
	)		(((uint32_t)(x) & ~bit(y)) | (((uint32_t)(z) & 1U) << (uint32_t)(y)))

sets the bit y in x to the value z

hal_gpio_toggle_bit

#define hal_gpio_toggle_bit	(		x,
			y
	)		(((x) & ~bit(y)) | ((~(x)) & bit(y)))

Toggle the bit y in x
