Low Operating Power on V_DD
When V_DD supply voltage is in the range indicated by V_DD(LOP), the bit LOPVDD is set to “1”. As soon as V_DD >
V_DD(LOP) the bit LOPVDD is set to “0” after the first Standard Diagnosis readout.
If V_DD supply voltage is not present, a voltage applied to pins CSN or SO can supply the internal logic (not
recommended in normal operation due to internal design limitations).
