2-4 Memory Map of Tag
2) System area of I.CODE2 chip
(1) UID
(2) EAS
(3) AFI
2-12
This section describes a system area of I.CODE SLI chip. The system
area of I-CODE SLI chip is allocated in the other area rather than user
memory area.
Execute a specific command to access to the system area.
The processes in the system area are done by specific commands instead
of page number allocations.
Byte0
UID is a Tag-specific code and has been written into the memory during
the chip production process.
The IC is shipped with this page write-access inhibited; there is no way of
making this page rewritable by the user.
EAS mode: Inhibition/permission of EAS function
(e=0: EAS mode is disable; e=1: EAS mode is enable)
Byte１
The pages marked with "X" in the table above are reserved for future use.
AFI is special area for enabling the user to identify a Tag that is suitable
for a specific user application.
