In I2C static registers located in the system configuration area can be accessed with I2C

read and write commands with device select E2=1. Readable system areas could be read in

continuity.

I2C security session must first be open, by presenting a valid I2C password, to grant write

access to system configuration registers.

Table 8 shows the complete map of the system configuration area, as seen by RF and I2C

interface.
