Configuration Memory Values
This section describes each individual field in the configuration memory.
Atmel
these fields except for the Lot History Code field, which is permanently locked. Atmel programs the remainder of the
fields, including all of the configuration memory and user zones to ones prior to releasing the device from the factory.
Table 9, “Factory Programmed Fields,” summarizes device fields Atmel programs at the factory. A brief description of
each field follows.
Table 9.
This is an 8-byte wide register with content that Atmel defines. This register is read/write accessible prior to blowing the
FAB fuse, but becomes read-only after blowing the fuse.
This field is a 16-bit wide register with content that Atmel defines. This field is read/write accessible prior to blowing the
FAB fuse, but becomes read-only after blowing the fuse.
This field is a 16-bit wide register with open read/write access privileges at all times for testing basic communication to
the device. This field is free of all security constraints at all times.
This field is a 32-bit wide register with read/write access privileges for the customer to define its content. The content of
this field becomes read-only after blowing the PER fuse.
This field is a 64-bit wide register with content that Atmel defines. This field is read-only.
This field is a 128-bit wide register with read/write access privileges for customer to define its content. The content of
this field becomes read-only after blowing the PER fuse.
