13.4. Determining the Device Part Number at Run Time
In many applications, user software may need to determine the MCU part number at run time in order to
determine the hardware capabilities. The part number can be determined by reading the value of the Flash
byte at address 0xFFFE. 

The value of the Flash byte at address 0xFFFE can be decoded as follows: 

0x56—C8051F930 
0x5E—C8051F931 
0xB1—C8051F920 
0xB3—C8051F921
