16.4.1.69 Offset 12Ch: RPERRCMD - Root (Port) Error Command Register
This register controls the generation of interrupts (beyond the basic root complex
capability to generate system errors) upon detection of errors. System error generation
in response to PCI Express* error messages may be turned off by system software
using the PCI Express* Capability Structure when advanced error reporting via
interrupts is enabled. These bits are sticky through reset.

FEIE
Fatal Error Interrupt Enable: Enables the generation of
an interrupt when a fatal error is reported by any of the
devices in the hierarchy associated with this Root Port. This
bit is sticky through reset.
Y
0 = Disable interrupt generation on fatal error.
1 = Enable interrupt generation on fatal error.
NEIE
Nonfatal Error Interrupt Enable: Enables the
generation of an interrupt when an nonfatal error is
reported by any of the devices in the hierarchy associated
with this Root Port. This bit is sticky through reset.
Y
0 = Disable interrupt generation on nonfatal error.
1 = Enable interrupt generation on nonfatal error.
CEIE
Correctable Error Interrupt Enable: Enables the
generation of an interrupt when a correctable error is
reported by any of the devices in the hierarchy associated
with this Root Port. This bit is sticky through reset.
Y
0 = Disable interrupt generation on correctable error.
1 = Enable interrupt generation on correctable error.
