The EEPROM data can be read, written, and erased through the serial interface. The boost converter is used to
generate the write and erase voltage for the memory. All operations are done in page mode. The page address
has to be written in the EEPROM_control register before access to the EEPROM. Incremental access can be
used both in I2C and SPI modes to speed up access. During EEPROM access the <rgb_auto> control bit in rgb
control register must be low.
