2. The group 1 and 2 can be selected by DZFM2-0 bits if P/S = “L” and DZFE = “L”.
3. This pin becomes OVF pin if OVFE bit is set to “1” at serial control mode.
4. All input pins should not be left floating.

This pin goes to “H” if the analog input of Lch or Rch is overflows.
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data,
this pin goes to “H”.
this pin goes to “H”.
“L”: Serial control mode, “H”: Parallel control mode
Large external capacitor around 2.2µF is used to reduce power-supply noise.
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data,
This pin should be connected to DVDD at I
I2C = “L”: CCLK (3-wire Serial), I2C = “H”: SCL (I
Enables digital loop-back from ADC to 3 DACs.
I2C = “L”: CDTI (3-wire Serial), I2C = “H”: SDA (I
Enables all 3 DAC channels to be input from SDTI1.
