Dear Sirs,
I have a question about OTP header area.
I want to set the data which size total is 17 bytes on the OTP header area.
I know, it is usable from 0x47F54 to 0x47F60, but the chip maker said following area can not use.
0 x47f5c
-0x47F60
-0x47FDC to 0x47FF0
If so, it is 9 bytes short.
I'm looking for the another memory address which can freely set data.
Could you tell me memory address or another solution?
Best Regards.

Hi Coral0310,
You can use the addresses in the OTP header from 0x47F44 up to 0x47F60 as smart snippets indicates as Custom fields.
Thanks MT_dialog
Dear Dialog staff,
Thank you for reply.
You said Customer specific fields is from 0x47F44 up to 0x47F60.
However the official document said that it is 0x47F54 to 0x47F60.
(Your answer is wider than the document.)
Why they are different? Has spec been updated?
This is a important point for our business.
So I need to see official announcement such as updated document,
website announcement or something like that.
Best Regards.
Hi Coral0310,
The spec has been updated, it specifies that the customer specific fields are even larger (from 0x47F10 up to 0x47F60 it includes the addresses indicated by smart snippets as reserved), i will check with the team if the new datasheet can be provided since its still under review.
Thanks MT_dialog
