This register controls the CPU Uncore responses to various system errors. Since the
CPU Uncore does not have an SERRB signal, SERR messages are passed from the CPU
Uncore to the SouthBridge over DMI.
CPU Uncore does not have an SERRB signal, SERR messages are passed from the CPU
Uncore to the SouthBridge over DMI.
When a bit in this register is set, a SERR message will be generated on DMI whenever
the corresponding flag is set in the ERRSTS register. The actual generation of the
the corresponding flag is set in the ERRSTS register. The actual generation of the
SERR message is globally enabled for Device #0 via the PCI Command register.

SERR on CPU Uncore Thermal Sensor Event
(TSESERR):
1: The CPU Uncore generates a DMI SERR
special cycle when bit 11 of the ERRSTS is set.
The SERR must not be enabled at the same
time as the SMI for the same thermal sensor
event.
0: Reporting of this condition via SERR
messaging is disabled.
(TSESERR):
1: The CPU Uncore generates a DMI SERR
special cycle when bit 11 of the ERRSTS is set.
The SERR must not be enabled at the same
time as the SMI for the same thermal sensor
event.
0: Reporting of this condition via SERR
messaging is disabled.

9 RW 0b Core
SERR on LOCK to non-DRAM Memory
(LCKERR):
1: The CPU Uncore will generate a DMI SERR
special cycle whenever a CPU lock cycle is
detected that does not hit DRAM.
0: Reporting of this condition via SERR
messaging is disabled.
(LCKERR):
1: The CPU Uncore will generate a DMI SERR
special cycle whenever a CPU lock cycle is
detected that does not hit DRAM.
0: Reporting of this condition via SERR
messaging is disabled.
8 RW 0b Core
SERR on DRAM Refresh Timeout
(DRTOERR):
1: The CPU Uncore generates a DMI SERR
special cycle when a DRAM Refresh timeout
occurs.
0: Reporting of this condition via SERR
messaging is disabled.
(DRTOERR):
1: The CPU Uncore generates a DMI SERR
special cycle when a DRAM Refresh timeout
occurs.
0: Reporting of this condition via SERR
messaging is disabled.
