4.2. Digital Programmable Gain/Attenuation
See functional description sections of digital programmable gain/attenuation for guidelines on computing register
values. All values are represented in twos-complement format.
Note: The values of all indirect registers are undefined following the reset state. Shaded areas denote bits that can be read
