Flash Memory
The XC82x has an embedded user-programmable non-volatile Flash memory that
allows for fast and reliable storage of user code and data. It is operated with a single
2.5 V supply from the Embedded Voltage Regulator (EVR) and does not require
additional programming or erasing voltage. The sectorization of the Flash memory
allows each sector to be erased independently.
