     I am working with mpc8360, I m using UCC as USART and UART, uart is working in loopback mode(GUMR_L[DIAG] = 0x01).

     if I made normal mode i.e(GUMR_L[DIAG] = 0x00). then I will not get the status in transmitter buffer i.e Ready bit in buffer will always high(1);

     same code if I made loopback its working.


     kindly give some guidance.


thank you
