Hi again!

I'm sorry, may be I described my problem unclear. So I'll try again.

I looked through HAL files, there are following files, which define all uart functions: altera_avalon_uart.h and (*.c), altera_avalon_uart_regs.h and (*.c). How can I use functions from these files - alt_avalon_uart_irq and e.t?

I just want to catch the moment, when UART receives data - rxdata.

How can I do it using interrupt handler or something else way?

Thank you
