(5) Configure the PM BEEP IN pin of BA7786FP-Y as
shown below in order to prevent oscillation in the IC.
(6) The LCH OUT pin (pin 8) of BA7786FP-Y should be
grounded when not used.
(7) When switching the suspend function popping nois-
es may occur. If this bothers, take measures for elimi-
nating it by attachig external componets.
