Note:
26/171
If a programming cycle is interrupted (by a RESET action), the memory data will not be
guaranteed.
Data EEPROM readout protection
The readout protection is enabled through an option bit (see
When this option is selected, the programs and data stored in the EEPROM memory are
protected against readout (including a re-write 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.
