1. Code on 7 bits.
Note: In response to a SDD_REQ Command with a SEL_PAR value equal to 20h, the
ST25TA16Ks in the Operating Field transmit the requested cascade level of their NFCID1
(NFCID1 CLn, with n = 1 or 2). The NFCID1 of the ST25TA16K 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 in
Table 48 for more
details.
