Traceability Data
A valid Write command can be used for programming a data block of 33 bits – including the
associated lock bit – into an addressed location of either memory section. Once locked
(lock bit = 1), the entire block including the lock bit itself can no longer be reprogrammed
selectively.
The system memory section is situated at the upper end of the (6-bit) memory address range
and contains all system parameters and configuration settings. This area has restricted access
(see
cessful execution of the appropriate Password Login command (see
All the configuration settings are allocated in block 63 (see
word protection security information in block 62 (see
The traceability information is programmed and locked into the traceability blocks (59-61) by
Atmel during the production test
