After power on reset, W6692A automatically reads the configuration data from serial EEPROM interface. The first word read
is Vendor ID. If Vendor ID = FFFF
H
, W6692A assumes EEPROM is empty and will use built-in default configuration data,
otherwise, configuration data from EEPROM is used. Please refer to Section 7.9.1 for serial EEPROM data format.
