Register Bits to EEPROM Mapping

Register bits settings are mapped into EEPROM. EEPROM is divided into three segments:

  • EEPROM Base Page: Selectable by connecting HW_SW_CTRL pin either to Logic 0 to Logic 1.
  • EEPROM Page 0: Selectable by connecting HW_SW_CTRL pin to Logic 0.
  • EEPROM Page 1: Selectable by connecting HW_SW_CTRL pin to Logic 1.
