1. “X” means “don’t care”.
2. The description of these modes is in the following
3. VEXT is the regulator output voltage obtained using the switching regulator controller with external FET.
Basic device mode
The basic device mode is selected by leaving the GPIO[0] pin floating. In this mode L6460
doesn’t use GPIO[3] and GPIO[4] as configuration pins, leaving them free for other uses.
When in this mode the regulators included in the start up sequence (except V
considered as system regulators and they start in the following sequence:
