(E)-7ɹSoftware reset
ɹɹ The servo processing is initialized if data of AAh address is accessed. DSP processing starts with the
first address.ɹɹɹɹɹɹɹɹɹɹɹɹɹɹ

Note) ɾThe VDET monitor signal is not set to H when the forced gain-up command is issued.
ɾThe status of the VDET can be monitored through the VDETMON pin.
ɾThe output of the VDETMON pin varies from H to L when vibration is detected even
in the forced gain-up mode. Then, this mode is not reset.
