Checklist Items Recommendations Reason/Impact
EE_DOUT Prototype Boards should include a placeholder
for a pull-down resistor* on this signal line, but
do not populate the resistor. Connect to
EE_DIN of EEPROM or CNR Connector.
ICH3-M contains integrated pull-up
resistor for this Signal.
Connected to EEPROM data input signal
(Input from EEPROM perspective and
output from ICH3-M perspective.)
EE_DIN No extra circuitry required. Connect to
EE_DOUT of EEPROM or CNR Connector.
ICH3-M contains integrated pull-up
resistor for this Signal.
Connected to EEPROM data output
signal.
(Output from EEPROM perspective and
input from ICH3-M perspective.)
NOTE: * If resistor is stuffed the value is 1 Kohm 5%
