Reading OTP Header

Hi all, I'm just starting to work on creating a production test application for our product and I would like to clarify some items about the OTP header.

1. Is the CLI tool able to read the entire OTP header or just the BD address?
2. If it is able to read the entire OTP what is the behavior of the reserved bits in OTP. Will it be able to return the reserved bytes or must I read only the non-reserved data?

Hi fitz,

Hi fitz,

1. Yes the CLI tool is able to read the entire OTP header and not just the BD address.

2. I dont quite get the second question, the command that the CLI implements will read all the data from the header and will write them into a file, the data that are allready burned will also pass into the file.

You can check the "help" option in the Smart Snippets Toolbox and through that you will be able to open the User Guide of the Smart Snippets toolbox, the pdf includes how to use the CLI and the available commands.

Thanks MT_dialog

Thanks for the quick reply!

Thanks for the quick reply! With regards to #2 I was just trying to understand if I can read the OTP header as one block including the reserved section. In other words is the reserved section read only or no access?

Hi fitz,

Hi fitz,

I suppose that you mean some fields that are indicated as reserved for future use, there is no restriction in reading those fields, you should be able to read them, they will just return zeros.

Thanks MT_dialog
