I'm using PA3 as EXTI3
Once the interruption enters, I need to read pulses (data) from PA3
I read the data in HAL_GPIO_EXTI_Callback. These are 24 bits which could be 24 pulses after the first one. The first one only indicates the beginning of the communication (interruption for attending the communication)
Is every new edge a new interruption? or
while the HAL_GPIO_EXTI_Callback is being executed, is the interruption inhibited?
