The EEPROM configuration memory stores the EEPROM settings, and the EEPROM settings configure the BM78 module firmware behavior. The IS1678 UI tool allows users to edit the configurable EEPROM setting and generates the output as a structured text file. The IS1678 UI tool also allows users to download the structured text file into the EEPROM memory. In addition to the IS1678 UI tool, the host MCU can also upgrade the EEPROM settings. With either the IS1678 UI tool or with the host MCU, the EEPROM upgrade procedure uses the same protocol as described in the following sections.
