PCI Express* Controller (x8) Registers
13.59 PEG Correctable Error Status—Offset 1D0h
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. Software may clear
an error status by writing a 1 to the respective bit. This register is for test and debug
purposes only.
Note: Corner cases exist where bogus errors can get logged in this register on the L0 to
Recovery transition where TS1 packets could be flagged as errors.
