TMS320C6748: McBSP connection with Codec AIC32xx and configuration

Part Number: TMS320C6748

AIC32xx Codec has only one BCLK and FS singal, when AIC32xx act as master, how to connect Codec with McBSP to work in duplex mode?

#1. connect McBSP CLKX and CLKR together, connect FSR and FSX together?

#2. Connect only CLKX to BCLK, FSX to FS, leave McBSP CLKR and FSR unconnected? and configure as below snapshot? in the DLB mode, receiver can share clock and FS with transmitter, but DX and DR also connected internally. so this configuration doesn't work.

Regards. Tony Tang
