ll_gpio_deinit()

error_status_t ll_gpio_deinit

(

gpio_regs_t *

GPIOx

)

De-initialize GPIO registers (Registers restored to their default values).

Parameters

GPIOx

GPIO instance.

Return values

An	error_status_t enumeration value: SUCCESS: GPIO registers are de-initialized ERROR: GPIO registers are not de-initialized

ll_gpio_init()

error_status_t ll_gpio_init	(	gpio_regs_t *	GPIOx,
		ll_gpio_init_t *	p_gpio_init
	)

Initialize GPIO registers according to the specified parameters in p_gpio_init.

Parameters

GPIOx	GPIO instance.
p_gpio_init	Pointer to a ll_gpio_init_t structure that contains the configuration information for the specified GPIO peripheral.

Return values

An	error_status_t enumeration value: SUCCESS: GPIO registers are initialized according to p_gpio_init content ERROR: Problem occurred during GPIO Registers initialization

ll_gpio_struct_init()

void ll_gpio_struct_init

(

ll_gpio_init_t *

p_gpio_init

)

Set each field of a ll_gpio_init_t type structure to default value.

Parameters

p_gpio_init

Pointer to a ll_gpio_init_t structure whose fields will be set to default values.

Return values

None
