from corresponding antifuse element and this way, its 3 V NMOS gate is protected
from the high voltage of VOTP during permanent write operation. This means that as
long as the VOTP voltage reads more than 3 V, the signal RD should be set.

information. For debug or calibration purposes it is possible to select channel 2 as
source of current channel signal when the tamper module is disabled. This is done

reading of the last four data records as first and the first four as second. The reading
sequence will be 5, 6, 7, 8, 1, 2, 3, 4. Differently from the other mode signals, the
precharge command is not retained inside the STPM01, in fact it should be sent each
time before the reading of the data records. This is the only command that can be
sent to STPM01 when the TSTD bit has been set.
