__HAL_GPIO_EXTI_GET_FLAG
Description:
Checks whether the specified EXTI line
flag is set or not.
Parameters:
__EXTI_LINE__: specifies the EXTI line
flag to check. This parameter can be
GPIO_PIN_x where x can be(0..15)
Return value:
The: new state of __EXTI_LINE__ (SET or
RESET).
__HAL_GPIO_EXTI_CLEAR_FLAG
Description:
Clears the EXTI's line pending flags.
Parameters:
__EXTI_LINE__: specifies the EXTI lines
flags to clear. This parameter can be any
combination of GPIO_PIN_x where x can
be (0..15)
Return value:
None
__HAL_GPIO_EXTI_GET_IT
Description:
Checks whether the specified EXTI line is
asserted or not.
Parameters:
__EXTI_LINE__: specifies the EXTI line to
check. This parameter can be
GPIO_PIN_x where x can be(0..15)
Return value:
The: new state of __EXTI_LINE__ (SET or
RESET).
