Auto-Initialization from EEPROM
The SiI3114 initiates the EEPROM detection and configuration space loading sequence after the Flash read
sequence. The SiI3114 supports up to 256-byte EEPROM with a 2-wire serial interface. The sequence of
operations consists of the following.
1.
START condition defined as a high-to-low transition on SDAT while SCLK is high.
2.
Control byte = 1010 (Control Code) + 000 (Chip Select) + 0 (Write Address)
3.
Acknowledge
4.
Starting address field = 00000000.
5.
Acknowledge
6.
Sequential data bytes separated by Acknowledges.
7.
STOP condition.
While the sequence is active, the SiI3114 responds to all PCI bus accesses with a Target Retry.
