R3: Record Power Management, 16,393 (0x4009)

This register manages the power consumption for the record path. In particular, the current distribution for the mixer boosts, ADCs,

record path mixers, and PGAs can be set to one of four modes. These settings are normal operation, power saving mode, enhanced

performance mode, and extreme power saving mode. Each of these modes draws current from a central bias. Enhanced performance

mode offers the highest performance with the trade-off of higher power consumption.
