Functional description
L5988D
The circuitry related to the UOS multifunction pin is composed of a 3 bit A/D converter and
the decoding logic. Table 6 shows the internal thresholds of each voltage window
composing the VREF magnitude. The voltage biasing of the multifunction can be set
accordingly to table Table 7.
