      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

      boost-peak-milliamp, boost-ind-nanohenry and boost-cap-microfarad.

      0 = Internal Boost

      1 = External Boost

      2 = Shared Boost Active

      3 = Shared Boost Passive
