Unique ID
STM8 devices feature a 96-bit unique device identifier which provides a reference number
that is unique for any device and in any context. The 96 bits of the identifier can never be
altered by the user.
The unique device identifier can be read in single bytes and may then be concatenated
using a custom algorithm.
The unique device identifier is ideally suited:
