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
