PCI Express Interface Controller
normally; however, write operations can clear but not set bits. A bit is cleared whenever the register is
written, and the data in the corresponding bit location is a 1. For example, to clear bit 6 and not affect any
other bits in the register, the value 0b0200_0000 is written to the register. When an error is detected the
appropriate error bit is set. Subsequent errors will set the appropriate error bits in the error detection
registers, but only the first error for a particular unit will have any relevant information captured. The
interrupt enable bits are used to allow or block the error reporting to the interrupt mechanism while the
disable bits are used to prevent or allow the setting of the status bits.

Multiple errors. Detecting multiple errors of the same type. An error is considered as multiple error when its
detect bit is set and the same error is occurring again. Note that this bit does not track the ordering of when
the error occurs.
1 Multiple errors were detected.
0 Multiple errors were not detected.
Reserved
PCI Express completion time-out. A completion time-out condition was detected for a non-posted,
outbound PCI Express transaction. An error response is sent back to the requestor.
1 A completion time-out on the PCI Express link was detected.
0 No completion time-out on the PCI Express link detected.
Reserved
PCI Express completer abort (CA) completion. A completion with CA status was received.
1 A completion with CA status was detected.
0 No completion with CA status detected.
PCI Express no map. Detect an inbound transaction that was not mapped to any inbound windows. In RC
mode, a completion without data (Cpl) packet with a UR completion status is sent back to the requester and
this bit is set. For EP mode, a Cpl packet with a UR completion status is sent back to the requester but will
not set this bit.
1 A no-map transaction was detected in RC mode.
0 No no-map transaction detected.
