12.9 Interface Module to Serial EEPROM
The Interface Module implements the protocol to allow the PCI core to connect to
a serial EEPROM.
the EEPROM can occur. If HRST* is applied while the EEPROM is being
accessed, that is, right after HRST* goes inactive, the access is abnormally
terminated with indeterminate effects on the EEPROM. In order to reset the
EEPROM, its power must be cycled. A 12 mA pin, EEPWR is added to supply
power to the EEPROM if the above condition cannot be guaranteed from
happening. Whenever HRST* is active, EEPWR is a logic low. When HRST*
goes to a logic high (inactive), EEPWR immediately goes to a logic high.
