About EEPROM access of DS80PCI402 & DS80PCI102, are following operations right?

・Power up.

・REANEN# signal：High→Low

・Device became I2C master, and EEPROM reading.

But, once EEPROM read, device wasn't read EEPROM again.

(EEPROM does not read, even if it carries out "REANEN# signal:High→Low".)

Is this operation right?

When right, is there any method of read EEPROM again?

Best regards,

Hi Satoshi-san,

Yes, that is the correct behavior. Thus far, the only way to have the device read from EEPROM again is to perform a power cycle to restart an EEPROM load.

Please check to see if the ALL_DONE# pin ever goes low. If it does not go low, there is a chance that the EEPROM was not burned properly.

Thanks,

Michael
