Shared USART3_8_IRQHandler source differentiation

Question asked by Rutherford.Christoph on Apr 10, 2017

Using the STM32 HAL API, I am using the HAL interrupt UART receive function 'HAL_UART_Receive_IT'.    In this case I am using UART6, because of this I have to use shared uart 3-8 interrupt handler 'USART3_8_IRQHandler(void)'.  If I wanted to use UART 4 and UART 6, when in the IRQ handler, how would I determine the UART source, so that I can correctly deal with the UART's data? 


Edit: Using STM32f091.
