Reserved. 

5:5

RO

0x0

transactions_pending:

Does not apply to Root/DMI ports, that is, bit hardwired to 0 for these 

devices.

4:4

RO

0x0

aux_power_detected:

Does not apply to the IIO.

3:3

RW1C

0x0

unsupported_request_detected:

This bit indicates that the root port or DMI port detected an Unsupported 

Request. Errors are logged in this register regardless of whether error 

reporting is enabled or not in the Device Control Register.
1: Unsupported Request detected at the device/port. These unsupported 

requests are NP requests inbound that the root port or DMI port received and 

it detected them as unsupported requests (for example, address decoding 

failures that the root port detected on a packet, receiving inbound lock reads, 

BME bit is clear and so forth).
0: No unsupported request detected by the root or DMI port
Note: This bit is not set on peer-to-peer completions with UR status that are 

forwarded by the root port or DMI port to the PCIe/DMI link.

0x0

fatal_error_detected:

This bit indicates that a fatal (uncorrectable) error is detected by the root or 

DMI port. Errors are logged in this register regardless of whether error 

reporting is enabled or not in the Device Control register.
1: Fatal errors detected
0: No fatal errors detected

1:1

RW1C

non_fatal_error_detected:

This bit gets set if a nonfatal uncorrectable error is detected by the root or 

DMI port. Errors are logged in this register regardless of whether error 

reporting is enabled or not in the Device Control register.
1: Nonfatal errors detected
0: No nonfatal errors detected

0:0

This bit gets set if a correctable error is detected by the root or DMI port. 

Errors are logged in this register regardless of whether error reporting is 

enabled or not in the PCI Express Device Control register.
1: Correctable errors detected
0: No correctable errors detected
