hello ,I have a question,when I used mcbsp rx in omap 3530,I set rx and tx to be master mode, and set the pin dx connect to pin rx ,when  CLKX and FSX signals is running, but the pin rx did not found a date. on the other hand ,I Configure the loopback mode , I found a date,so I have a question,in the rx master mode ,the receiver how to working.

    Check the pad configuration register settings for that pin and ensure the INPUTENABLE bit is set to enable the input stage of the I/O for the particular pin.

    This is a common oversight.  I would also suggest the same for the CLK and FSX as well.
