6.7 Signature Bytes
All tinyAVR® microcontrollers have a 3-byte signature code that identifies the device. The three bytes reside in a separate address space. For the device, the signature bytes are given in the following table.
Note: When the device is locked, only the
System Information Block (SIB) can be accessed.
