Note:
Command
SENS_REQ or ALL-REQ
In response to a SDD_REQ Command with a SEL_PAR value equal to 20h, ST25TA02K-D in the Operating Field transmit the requested cascade level of their NFCID1 (NFCID1 CLn, with n = 1 or 2). The NFCID1 of ST25TA02K-D consists of 7 bytes. The length of the
Response containing a complete NFCID1 cascade level (i.e., NFCID1 CL1, or NFCID1 CL2) is always 5 bytes. The coding of the Response depends on the value of the SEL_CMD byte and the size of the NFCID1.
Refer to the example below for more details.
