NOTE: EEPROM organization must be big EndianMS byte of data word allocated to the lowest address in memory.
The I2C master mode also utilizes the starting and ending I2C check words to verify a proper EEPROM download.
The first 32-bit data word received from the EEPROM, the starting I2C check word at subaddress 0x00, is stored and
compared against the 32-bit data word received for subaddress 0xFC, the ending I2C check word. These two data
words must be equal as stored in the EEPROM. If the two words do not match when compared in the TAS3103, the
TAS3103 conducts another parameter download from the EEPROM. If the comparison check again fails, the
TAS3103 discards all downloaded parameters and set all parameters to the default values listed in the subaddress
table presented in the Appendix. In the I2C slave mode, these default values are used to initialize the TAS3103 at
power turnon or after a reset.
