18.4. 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
DEVICEID Special Function Register.

The value of the DEVICEID register can be decoded as follows:

0xD0—C8051F960
0xD1—C8051F961
0xD2—C8051F962
0xD3—C8051F963
0xD4—C8051F964
0xD5—C8051F965
0xD6—C8051F966
0xD7—C8051F967
0xD8—C8051F968

Device Identification.
These bits contain a value that can be decoded to determine the device part
number.
Revision Identification.
These bits contain a value that can be decoded to determine the silicon 
revision. For example, 0x00 for Rev A and 0x01 for Rev B, etc.
