The TPS65033000-Q1 contains EEPROM (Electronically Erasable Programmable Read Only Memory) that is read on power-up to set the default register settings. For more details on the device EEPROM and registers, request device documentation through the TPS650330-Q1 product page.

Several features offer protection against unintended changes to the device registers and EEPROM.

1. Control lock register: A specific value must be written to this register to unlock the device control registers for modification.
2. Config lock register: A specific value must be written to this register to unlock the device configuration registers for modification.
3. Configuration CRC: The device continuously compares the current configuration register settings against the expected configuration register settings. If there is a mismatch, the device registers an error and generates an interrupt.
4. Program EEPROM register: A specific value must be written to this register to reprogram the device EEPROM.
