General command rules

In case of a valid command, the following paragraphs will describe the expected behavior for each command.

But in case of an invalid command, in a general manner, the ST25DVxxx will behave as follows:

if flag usage is incorrect, the error code 03h will be issued only if the right UID is used in the command,

otherwise no response will be issued.

error 02h will be issued if the custom command is used with the manufacturer code different from the ST

one

Another case is if I2C is busy. In this case, any RF command (except Inventory, Select, Stay quiet and Reset to

ready) will get 0Fh error code as response only:

•

if select flag and address flags are not set at the same time (except if ST25DVxxx is in quiet state)

•

if select flag is set and ST25DVxxx is in selected state.

For all other commands, if I2C is busy, no response will be issued by ST25DVxxx.
