AIC33 or DM6446 who is the Master ?

Hi all,

In my DM6446 EVM I want to connect some other codecs or bluetooth modules to DX, DR, FCLK and BCLK lines. I read the application report (SLAA301) which is about interfacing 4 AIC33 in TDM mode. However I want to learn:

-Who is the master in DM6446 EVM? (DM6446 or AIC33)

-Can DM6446 be used as master mode in multiple codec/bluetooth module implementation in TDM mode?

-Do you have any suggestion in hardware connection? (Which should be the master in multiple codec/bluetooth module connection?)

 

Thank you for any suggestions..

Ferhat
