HIGH VOLTAGE TOLERANT PINS
In many applications, the High Voltage will
only be present at the manufacturing
stage so as to “lock” the Non-Volatile wiper
value (after calibration) and the contents
of the EEPROM. This ensures that since
High Voltage is not present under normal
operating conditions, these values can not
be modified.
