6.3.3 REGISTER INITIALISATION FILE (READ/WRITE)
The content of the E²PROM memory from block address 3 to 7 may be used to initialise the CL RC632
registers 10_hex to 2F_hex by execution of the LoadConfig-Command (see 18.7.1). It requires a two bytes
argument, used as the two bytes long E²PROM starting byte address for the initialisation procedure.
The assignment is the following:
E²PROM Byte Address
Starting Byte address for the E²PROM
Starting Byte address for the E²PROM +1
…
Starting Byte address for the E²PROM + 31
Register Address
10_hex
11_hex
…
2F_hex

Table 6-6: Byte Assignment for Register Initialisation at Start Up
The Register Initialisation File is big enough to hold the values for two initialisation sets and leaves one more
block (16 bytes) for the user.
Note: The Register Initialisation File is read- and write-able for the user. Therefore, these bytes may also be
used to store user specific data for other purposes.
The standard configuration for the CL RC632 enables the MIFARE® and ISO14443 setting after each power
up.
To give the user the needed flexibility the startup configuration might be adapted and for example the
ICODE1 start up configuration might be stored in the register block address 3 and 4.
