Automatic emergency deactivation is performed in the following cases:
If the reason of the deactivation is a card take off, an overcurrent or an overheating, then
INT0_N is LOW. The corresponding bit in the hardware status register is set. Bit START is
automatically reset.
If the reason is a supply dropout, then the deactivation sequence occurs, and a complete
reset of the chip is performed. When the supply will be OK again, then the bit SUPL will be
set in HSR.
