4.2.5 Various Settings
This section describes the parameter settings and operation specifications based on JISX6319-4 for this
RFID.
4.2.5.1 System Code
System code is a parameter specified by the REQ command that is used to identify the RFID. Figure 4-5
shows the system code. The system code is set by the value of the system area SC for FeRAM.
The response operation to the REQ command by system code is shown in Table 4-3.

RFID's response to REQ command
Responds regardless of the system area SC setting
When the value of the upper 1 byte of the SC system area
is 0xAA, the RFID responds regardless of the value of the
lower 1 byte.
Responds only when the setting value of the REQ
command's system code matches the value specified in
the system area SC (and does not respond in other cases).
4.2.5.2 PICC (Proximity IC Card) Identifier
The PICC (Proximity IC Card) identifier is a data used to identify RFID, and is included in the response to the
REQ command. Figure 4-6 illustrates the PICC identifier's format. The PICC identifier (8 bytes) is set in the
system area IDM.
