Problem with C6713's McBSP interfacing with an I2S CODEC

Started by Jessecw May 31, 2007
Hi All,

     I am going to connect an audio CODEC with C6713. And the CODEC
has no DSP mode. So I want to use McBSP as an I2S bus.

     Here are parts of my schematic.

     DSP C6713:                 CODEC:
     CLKX1----------+
                           +------------MCLK (bit clock signal)
     CLKR1----------+

     FSX1-----------+
                          +------------LRCK
     FSR1-----------+

     Here is an example McBSP setting from TI's TMS320C6000 McBSP: I2S
Interface.
     FSX is output pin
     FSR is output pin
     CLKX is output pin
     CLKR is output pin

     My question is: If all pins are set as output pin, will CLKR1 or
FSR1 work properly? or Are there any problems with my schematic?

     Thanks in advance.

Jesse

Sorry forget to say that "+" means connected together.

Thanks

Jesse
