Host-PCI Express* Bridge Registers (D1:F0) (Intel® 82945G/82945GC/82945P/82945PL Only) 5.1.60 UEMSK—Uncorrectable Error Mask (D1:F0) Bus/Dev/Func/Type: 0/1/0/MMR Address Offset: 1C8–1CBh Default Value: 00000000h Access: RO, R/W/S Size: 32 bits This register controls reporting of individual errors by the device (or logic associated with this port) to the PCI Express Root Complex. As these errors are not originating on the other side of a PCI Express link, no PCI Express error message is sent, but the unmasked error is reported directly to the root control logic. A masked error (respective bit set to 1 in the mask register) has no action taken. There is a mask bit per error bit of the Uncorrectable Error Status register.

5.1.61 CESTS—Correctable Error Status (D1:F0) Bus/Dev/Func/Type: 0/1/0/MMR Address Offset: 1D0–1D3h Default Value: 00000000h Access: RO,R/WC/S Size: 32 bits Host-PCI Express* Bridge Registers (D1:F0) (Intel® 82945G/82945GC/82945P/82945PL Only) This register reports error status of individual error sources on a PCI Express device. An individual error status bit that is set indicates that a particular error occurred. Note: Software clears an error status by writing a 1 to the respective bit.
