I²C_SAM_Address: The I²C SAM Address is always defined by the EEPROM content.
: The Register Set Protocol (RSP) Area contains settings for the TX registers (16 bytes)
and for the RX registers (8 bytes).

8.7.3 EEPROM initialization content LoadProtocol
The CLRC663 EEPROM is initialized at production with default values which are used to
reset the registers of the CLRC663 by copying the EEprom content to the registers. Note
that the addresses used for copying reset values from EEprom to registers are dependent
on the configured protocol and can be changed by the user.
