MOTOROLA
The Flash module provides the necessary security information to the
rest of the chip. This information is stored within a byte in the Flash block
0 ($FF0F). This byte is read automatically after each reset and stored in
a volatile register - FSEC. This information also protects the Flash
Flash EEPROM 64K
