14.4. 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—C8051F990
0xD1—C8051F991
0xD6—C8051F996
0xD2—C8051F997
0xD3—C8051F980
0xD4—C8051F981
0xD5—C8051F982
0xD7—C8051F983
0xD8—C8051F985
0xD9—C8051F986
0xDA—C8051F987
0xDB—C8051F988
0xDC—C8051F989
