Enable all 3 DAC channels to be input from SDTII.
Notes : 1. SDOS, SMUTE, DFS, and LOOP1 pins are ORed with register data if P/S = "L".
2. The group 1 and 2 can be selected by DZFM2-0 bit if P/S = "L" and DZFME = "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.

Function
No internal bonding.
When the input data of the group 1 follow total 8192LRCK cycles with "0" input data,
this pin goes to "H".
This pin goes to "H" if the analog input of Lch or Rch is overflows.
"L" : Serial control mode, "H" : Parallel control mode
Enables digital loop-back from ADC to 3 DACs.
I2C = "L" : CDTI(3-wire Serial), I2C = "H" : SDA(I2CBus)
