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 SL RC400
registers 10_hex to 2F_hex by execution of the LoadConfig-Command (see 16.6.1). It requires a two byte
argument, that is used as the two byte 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
…
Register Address
10_hex
11_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.
