## Detailed Description

## Function Documentation

## ◆ ll_gpio_clear_flag_it()

__STATIC_INLINE void ll_gpio_clear_flag_it | ( | gpio_regs_t * | GPIOx,
|  | uint32_t | pin_mask
| ) |  |

Clear Interrupt Status flag for pins in the range of 0 to 15.

Note
  After an interrupt is triggered, the corresponding bit in the INTSTATUS Register is set. The interrupt status can be cleared by writing 1 to corresponding bit in INTCLEAR Register.

Register | BitsName
--- | ---
INTSTATUS | INTSTATUS

Parameters

  GPIOx | GPIO instance.
  pin_mask | This parameter can be a combination of the following values: LL_GPIO_PIN_0 LL_GPIO_PIN_1 LL_GPIO_PIN_2 LL_GPIO_PIN_3 LL_GPIO_PIN_4 LL_GPIO_PIN_5 LL_GPIO_PIN_6 LL_GPIO_PIN_7 LL_GPIO_PIN_8 LL_GPIO_PIN_9 LL_GPIO_PIN_10 LL_GPIO_PIN_11 LL_GPIO_PIN_12 LL_GPIO_PIN_13 LL_GPIO_PIN_14 LL_GPIO_PIN_15 LL_GPIO_PIN_ALL

Return values

  None |

## ◆ ll_gpio_is_active_flag_it()

__STATIC_INLINE uint32_t ll_gpio_is_active_flag_it | ( | gpio_regs_t * | GPIOx,
|  | uint32_t | pin_mask
| ) |  |

Indicates if the GPIO Interrupt Flag is set or not for pins in the range of 0 to 15.

Note
  After an interrupt is triggered, the corresponding bit in the INTSTATUS Register is set. The interrupt status can be cleared by writing 1 to corresponding bit in INTCLEAR Register.

INTSTATUS | INTSTATUS

Parameters

  GPIOx | GPIO instance.
  pin_mask | This parameter can be a combination of the following values: LL_GPIO_PIN_0 LL_GPIO_PIN_1 LL_GPIO_PIN_2 LL_GPIO_PIN_3 LL_GPIO_PIN_4 LL_GPIO_PIN_5 LL_GPIO_PIN_6 LL_GPIO_PIN_7 LL_GPIO_PIN_8 LL_GPIO_PIN_9 LL_GPIO_PIN_10 LL_GPIO_PIN_11 LL_GPIO_PIN_12 LL_GPIO_PIN_13 LL_GPIO_PIN_14 LL_GPIO_PIN_15 LL_GPIO_PIN_ALL

Return values

  State | of bit (1 or 0).
