Hello,
Recently I use UART0 of DM6437 to receive and send serial data, but a problem occured in my program. The UART0 works in FIFO mode. When I send serial data to DM6437 one byte by one byte,it will receive correctly. But if I send serial data to DM6437 too fast, an abnormal interrupt will be generated, and the register UART0_IIR whose address is 0x01C20008 will become 0xC6. The receiver of UART0 will not work unless I reload the program to DSP. And the transmitor works normally all the time. I wonder if you can give me a favor. Thank you very much!
