TAS2770: Getting TDM clock error and reg 0x77 sets to 0x7f

Hi Team 

I am able to get bitclock as 1.5Mhz and WS clock as 48KHz, properly.

But still tas2770 is going to SW shutdown. 

Our requirement is to play <Signed 16 bit Little Endian, Rate 48000 Hz, Mono>

Can you please say the i2c configurations for this?

Thanks 
Thiru
