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

and written but should be written to zeroes.
