Data EEPROM readout protection
The readout protection is enabled through an option bit (see option byte section).
When this option is selected, the programs and data stored in the EEPROM memory are
protected against read-out (including a rewrite protection). In Flash devices, when this
protection is removed by reprogramming the option byte, the entire Program memory and
EEPROM is first automatically erased.
Both program memory and data EEPROM are protected using the same option bit.
