PCM1809: automatic power-down and target mode pin configuration

Tool/software:

Hello Experts,

I have question as follows. Would you answer them, please?
1. Regrading automatic power-down in target mode, it is needed to stop BCLK only, correct? Or it is needed to stop both BCLK and FSYNC?
2. Regarding target mode, how to treat a MD1-pin? Can it be floating or pull-up/down is needed?

Best Regards,
Fujiwara
