EEPROM Programming
Changing the configuration of the TLE5014 without updating the corresponding checksum results in a CRC
error, which is indicated.

Verification of EEPROM
To verify if the programing of the EEPROM page was successful, the respective EEPROM page should be read
again and verified if the content matches with the intended content.
In addition, there is a register at address 0x69, which indicates the status after the EEPROM burning.
