Unsupported Request Detected (URD): When set, this bit indicates that the 
Device received an Unsupported Request. Errors are logged in this register 
regardless of whether error reporting is enabled or not in the Device Control 
Register.
Additionally, the Non-Fatal Error Detected bit or the Fatal Error Detected bit is 
set according to the setting of the Unsupported Request Error Severity bit. In 
production systems setting the Fatal Error Detected bit is not an option as 
support for AER will not be reported.

Fatal Error Detected (FED): When set, this bit indicates that fatal error(s) 
were detected. Errors are logged in this register regardless of whether error 
reporting is enabled or not in the Device Control register. When Advanced Error 
Handling is enabled, errors are logged in this register regardless of the settings 
of the uncorrectable error mask register.
