General Self-Test Result (SELF_TST) — R/W (special).
0 = Pass
1 = Fail
Reserved
Diagnose Result (DIAG_RSLT) — R/W (special). This bit provides the result of an internal
diagnostic test of the Serial Subsystem.
0 = Pass
1 = Fail
Reserved
Register Result (REG_RSLT) — R/W (special). This bit provides the result of a test of the internal
Parallel Subsystem registers.
0 = Pass
1 = Fail
ROM Content Result (ROM_RSLT) — R/W (special). This bit provides the result of a test of the
internal microcode ROM.
0 = Pass
1 = Fail

EEPROM Serial Data Out (EEDO) — RO. Note that this bit represents “Data Out” from the
perspective of the EEPROM device. This bit contains the value read from the EEPROM when
performing read operations.
EEPROM Serial Data In (EEDI) — WO. Note that this bit represents “Data In” from the perspective
of the EEPROM device. The value of this bit is written to the EEPROM when performing write
operations.
EEPROM Chip Select (EECS) — R/W.
0 = Drives the Intel
1 = Drives the ICH5’s EE_CS signal high, to enable the EEPROM.
EEPROM Serial Clock (EESK) — R/W. Toggling this bit clocks data into or out of the EEPROM.
Software must ensure that this bit is toggled at a rate that meets the EEPROM component’s
minimum clock frequency specification.
0 = Drives the ICH5’s EE_SHCLK signal low.
1 = Drives the ICH5’s EE_SHCLK signal high.
