BF706 low power mode PCM384 DSD256

Hi Guys:

      i wanna confirm some question about BF706.

1、Do we have any reference examples for the current low power consumption mode of bf706? I consider that we usually start with internal nuclear power and external IO power. By reducing the clock frequency of the kernel, we have turned off the external peripheral interface. If there is an example, I think it should be the best 。

2、At present, whether our bf706 supports the coding of pcm384 and dsd256?because our case is a portable hifi player, which requires the front-end input audio coding format.

     Looking forward to your reply!
