External Boost must have GPIO1 as GPIO output. GPIO1 will be set high to
enable boost voltage.
+ Shared boost allows two amplifiers to share a single boost circuit by
+ communicating on the MDSYNC bus. The active amplifier controls the boost
+ circuit using combined data from both amplifiers. GPIO1 should be
+ configured for Sync when shared boost is used. Shared boost is not
+ compatible with External boost. Active amplifier requires
