DM6437 UART

Hi all

I am using UART of DM6437 for serial communaication. The function GIO_read() is a blocking function. It blocks itself until it reads data from UART. I want to use either polling or ISR for receiving data from UART,

for Polling I checked the INTID bit in IIR register but it is not working correctly. How this can be done ???

Kindly help.

Regards

Saira

    When I read data directly from RBR register,,, GARBAGE vlaue is read. and by using GIO_read() the program blocks until it received data.

    How to configure UART to receive correct data and with non blocking calls....
