Sticky
Data Link Protocol Error Mask. When this bit is set, the corre-
sponding bit in the AERUES register is masked. When a bit is
masked in the AERUES register, the corresponding event is not
logged in the advanced capability structure, the First Error Pointer
field (FEPTR) in the AERCTL register is not updated, and an
error is not reported to the root complex.

AERUES register.

Sticky
Surprise Down Error Mask. When this bit is set, the correspond-
ing bit in the AERUES register is masked. When a bit is masked
in the AERUES register, the corresponding event is not logged in
the advanced capability structure, the First Error Pointer field
(FEPTR) in the AERCTL register is not updated, and an error is
not reported to the root complex.

in the AERUES register is masked. When a bit is masked in the
AERUES register, the corresponding event is not logged in the
advanced capability structure, the First Error Pointer field
(FEPTR) in the AERCTL register is not updated, and an error is
not reported to the root complex.

AERUES register.
13 FCPERR RW 0x0

responding bit in the AERUES register is masked. When a bit is
masked in the AERUES register, the corresponding event is not
logged in the advanced capability structure, the First Error Pointer
field (FEPTR) in the AERCTL register is not updated, and an
error is not reported to the root complex.
This bit does not affect the state of the corresponding bit in the
AERUES register.
