Specific RF command set
This section describes the command set that can be issued only by the RF host.
Anticollision command set
Table 46 lists the commands that can be issued only by the RF host. The format of these
commands is described in the NFC Forum Digital Protocol specification.

1. Code on 7 bits.
Note:
In response to a SDD_REQ Command with a SEL_PAR value equal to 20h, SRTAG2KL in
the Operating Field transmit the requested cascade level of their NFCID1 (NFCID1 CLn,
with n=1 or 2). The NFCID1 of SRTAG2KL 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 example below for more details .
