SIGNATURE 15 to 0

write signature to enter command mode; see Section 16.3.3

[1]

Undefined: write as zero for default, returns any value when read.

16.5.3 Non-volatile memory registers

The device includes several internal registers which are used for customization and

identification.

The initial signature allows read access to all areas but only write access to customer

registers. Write accesses to reserved areas are ignored. Since these registers are

implemented as non-volatile memory cells, writing to the registers needs a specific time

tprog after each write access to complete.

As there is no check for the programming time, make sure that no other accesses to

the non-volatile memory are made during the programming cycle. Do not address the

non-volatile memory during the time tprog.

Note: To calculate the corresponding checksum, read out all register addresses.
