Notes
(1) No more than 100 cumulated hours in life time above Ttsd
(2) Communication over serial bus is operating. Motordriver is disabled when Vbb < UV2
(3) Pin VDD must not be used for any external supply
(4) The RAM content will not be altered above this voltage

External resistance value seen from pin SWI or HW, including 1kΩ series resistor
If Input voltage ≤ -0.3 Volts, then a resistor of 22 to 100Ω must be added in series
In case 100 kHz ≤ fSCL ≤ 360kHz VIH min = 0.7VDD
