Re-Programming the EEPROM of the TPS65218D0 Device
This section provides an example of how to re-write the EEPROM of the TPS65218D0 device using the
IPG-UI and visually verify that the new values have been correctly programmed into the non-volatile
EEPROM memory of the device. The most commonly programmed values, DC/DC converter output
voltage and sequencing order, will be modified in this example.
NOTE:
All of the bits that are backed by EEPROM and are programmable are highlighted in red in
the Register Map section of the IPG-UI software for the TPS65218D0 device. Bits that are
grayed out are Reserved and are Read-Only. The bits with no color-coding are Read-Write
capable and can be edited in real-time, but this memory is volatile and the values will not be
stored when the TPS65218D0 device is power-cycled.

programmed.
