50/64

DocID027794 Rev 2

The ascending and descending data rates shall be coded as described in Table 53.

When the ST25TA02K-P is able to change both data rates, it returns the following response.

The data rate of this response is 106 kbps; then, the ST25TA02K-P changes the ascending

and descending data rates.

Table 54 gives the details of the PPS response.
