Note 1. It is recommended to use a resistor with 0.1% absolute error in Fs Auto Detect Mode.
Note 2. All input pins except for internal pull-up/down pins must not be left floating.
Note 3. Reset by PDN pin when changing control mode(Pin Control ⇔ Register Control) by PSN pin.
Note 4. PCM mode, DSD mode and EXDF mode are controlled by register settings.
