Analog Front-End
In ENABLE-16 mode, the aux-DACs have independent
control bits E4, E5, and E6, bit E7 sets the Tx path full-
scale ouputs, and bit E9 enables the aux-ADC. Table 7
shows the auxiliary DAC enable codes. Table 8 shows
the full-scale output selection. Table 9 shows the auxil-

iary ADC enable code. Bits E11 and E10 are reserved.
Program bits E11 and E10 to logic-low.
Modes aux-DAC1, aux-DAC2, and aux-DAC3 select the
aux-DAC channels named DAC1, DAC2, and DAC3
and hold the data inputs for each DAC. Bits _D11–_D0
