Part Number: TLV320AIC3256EVM-U

Hi,

my system look like a picture below:

At now the EVM board config by default that the primary is amaster and i success to receive data from TLV to my STM but i dont know how to configure the secondary channel in TLV to be a slave

and to route the data to HP.

another Question:

I look on slau306a.pdf in page 73 to understand which line to use to configure the secondary but i see that BCLK, WCLK and DOUT(DIN of TI) can be S_CLK or GPIO only so I need 3 lines but have only 2?

can you help me to understand which registers i need to change to configures the master or slave?

thanks!!!
