Interface bits...continued 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). Section Section 4 TX Tx0 Tx1 TX2 Tx3 Section 4 TX Tx4 Tx5 TX6 TX7 Section 4 Rx RX0 RX1 RX2 RX3 RX4 RX5 RX6 RX7 Section 4 Rx RX8 RX9 RX10 RX11 RX12 RX13 RX14 RX15 Table 41. Tx and Rx arrangements in the register set protocol area TxCrcPreset The data bits are sent by the analog module and are automatically extended by a CRC. 8.7.3 EEPROM initialization content LoadProtocol The CLRC663 EEPROM is initialized at production with values which are used to reset certain registers of the CLRC663 to default settings by copying the EEPROM content to the registers. Only registers or bits with "read/ write" or "dynamic" access rights are initialized with this default values copied from the EEPROM. 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.
