6–1
6 Register Set
Bits D12 through D8 in a secondary serial communication comprise the address of the register that is written with
data carried in D7 through D0. D13 determines a read or write cycle to the addressed register. When low, a write cycle
is selected.
The following table shows the register map.

16-bit DAC mode (hardware secondary requests)
0
Not 16-bit DAC mode (software secondary requests) [(15+1)– bit mode]
Default value: 0 0 0 0 0 0 0 0
NOTE 1: These gains are for a single-ended input. The gain is 6 dB lower with a differential input.
A software reset is a one-shot operation and this bit is cleared to 0 after reset. It is not necessary to write a 0 to end
the master reset operation. Writing 0s to the reserved bits is suggested.
