3.3 Serial
EEPROM
A socketed 2 Kbit serial EEPROM (U6) is used
in this RDK. It is connected directly to the PCI
9054 and provides the configuration data to
initialize the PCI 9054 after the system reset.
There are 88 bytes of pre-programmed
configuration data in the serial EEPROM, which
include device and functional information for
plug-and-play (PnP), PCI memory resource
allocation, and initial values of internal registers.
