2.2 Device/Revision ID

The 14-bit Device ID register is located at 8006h and the 14-bit Revision ID register is located at 8005h. These locations are read-only and cannot be erased or modified.

Important:

If the ICSP interface has been disabled by setting the ICSPDIS configuration bit, the Device ID and Revision ID can still be read using the dedicated ICSP commands documented in Table 3-1. These commands will only return the Device ID and Revision ID if the ICSP and Debugging interfaces are locked, otherwise these commands will always return a constant value of 0xA5A5.
