ST25TA02K-P

RF command sets

5.1

Structure of the command sets

The exchange of data between the RF host and the ST25TA02K-P uses three kinds of data

formats, called blocks:

•

I-Block (Information block): to exchange the command and the response

•

R-Block (Receive ready block): to exchange positive or negative acknowledgement

•

S-Block (Supervisory block): to use either the Deselect command or the Frame Waiting

eXtension (WTX) command or response

This section describes the structure of I-Block, R-block and S-Block. This format is used for

the application command set.

5.2

I-Block format

The I-Block is used to exchange data between the RF host and the ST25TA02K-P. It is

composed of three fields. Table 12 details the I-Block format.
