3114 PCI to Serial ATA Controller
Data Sheet
Silicon Image, Inc.
Auto-Initialization
SiI
-DS-0103-D
22
2007 Silicon Image, Inc.
The
SiI
3114 supports an external flash and/or EEPROM device for BIOS extensions and user-defined PCI
configuration header data.
Auto-Initialization from Flash
The
SiI
3114
initiates the flash detection and configuration space loading sequence upon the release of
PCI_RST_N. It begins by reading the highest two addresses (7FFFF
H
and 7FFFE
H
), checking for the correct data
signature pattern — AA
H
and 55
H
, respectively. If the data signature pattern is correct, the
SiI
3114 continues to
sequence the address downward, reading a total of sixteen bytes. If the Data Signature is correct (55
H
at
7FFFC
H
), the last twelve bytes are loaded into the PCI Configuration Space registers.
Note:
If both flash and EEPROM are installed, the PCI Configuration Space registers will be loaded with the
EEPROM’s data.
While the sequence is active, the
SiI
3114 responds to all PCI bus accesses with a Target Retry.
