Hello, we are planning to connect empty(new) EEPROM to DP83816.
If EMPTY(All data are FFFFh) EEPROM is connected to DP83816, does DP83816 act under the same operation as the following Datasheet described?
In the other words, does "The EEPROM is not present" mean "EMPTY EEPROM is connected" ?
3.3.3 EEPROM
The DP83816 supports the attachment of an external EEPROM.
The EEPROM interface provides the ability for the DP83816 to read from and write data to an external serial EEPROM device.
The DP83816 will auto-load values from the EEPROM to certain fields in PCI configuration space and operational space and perform a checksum
to verify that the data is valid.
Values in the external EEPROM allow default fields in PCI configuration space and I/O space to be overridden following a hardware reset.
If the EEPROM is not present, the DP83816 initialization uses default values for the appropriate Configuration and Operational Registers.
Software can read and write to the EEPROM using “bit-bang” accesses via the EEPROM Access Register (MEAR).
