*2 Enabled/Disabled can be selected using commands.
*3 In STAND ALONE MODE (MODE1),
When ANALOG DAC output is selected (SEL_DOUT=H), LED output is enabled.
When the Digital output is selected (SEL_DOUT=L), the I2S format audio output is enabled.
In SLAVE MODE (MODE2, MODE3),
When the ANALOG DAC output is selected (SEL_DOUT=H), these pins are TEST terminals.
When the Digital output is selected (SEL_DOUT=L), you can select I2S format audio output or digital
