Start-up configurations
L6460 start-up configuration is selected by setting in different states the GPIO[0], GPIO[3]
and GPIO[4] pins. Each of these is a three state input pin and is able to distinguish among
the following situations:

“Shorted” means: R
Operation modes
When V
logic circuits inside the device, starts its functionality. When it reaches its final value, L6460
enables the GPIO[0] pin state read circuitry, and, after a time TpinSample, it will sample the
GPIO[0] state. If it is found to be in high impedance, L6460 does not consider GPIO[3] and
GPIO[4] pins state and starts its “Basic device” mode sequence. If GPIO[0] is found to be
connected to ground or to V3v3, L6460 checks the state of GPIO[3] and GPIO[4] pins to
select its start-up configuration.
The possible configurations can be classified in four “Major” modes:
