DESCRIPTION
0b: EEPROM autoload was unsuccessful or is disabled
1b: EEPROM autoload occurred successfully after PREST. Configuration
registers were loaded with values stored in the EEPROM
Reset to 0b.
0b: EEPROM autoload enabled
1b: EEPROM autoload disabled
Reset to 1b.
Determines the frequency of the EEPROM clock, which is derived from the
primary clock.
00b: Reserved
01b: PEXCLK / 1024 (PEXCLK is 125MHz)
10b: Reserved
11b: Test Mode
Reset to 01b.
DESCRIPTION
Reset to 0b.
Contains the EEPROM address.
Reset to 0.
DESCRIPTION
Contains the data to be written to the EEPROM. After completion of a read
cycle, this register will contain the data from the EEPROM.
Reset to 0000h.
DESCRIPTION
Read as 10h to indicate that these are PCI express enhanced capability
registers.
DESCRIPTION
Read as 00h. No other ECP registers.
DESCRIPTION
Read as 0001b to indicate the device is compliant to the PCI Express Base
Specifications.
