LPC Port Register Descriptions
5.14.1 LPC Specific MSRs
The LPC Controller uses the MSR_LPC_EADDR and MSR_LPC_ESTAT to record the indicated information associated
with any given LPC bus error. The recorded information can not be cleared or modified. Simultaneous with this recording,
an error event is sent to the DIVIL GLD_MSR_ERROR (MSR 51400003h). If enabled at the DIVIL GLD_MSR_ERROR, any
LPC error event is recorded with a flag. This flag can be cleared. The status of this flag should be used to determine if there
is an outstanding error associated with the two MSRs below.

Description
LPC Error Address. When an error occurs, this register captures the associated 32-bit
address.
Description
Reserved. Reads as 0.
Timeout. If set, indicates an LPC error was caused by a timeout.
DMA. If set, indicates an LPC error occurred during a DMA transaction.
Write. If set, indicates an LPC error occurred during an LPC write transaction.
Memory. If set, indicates an LPC error occurred during an LPC memory transaction.
