14.8.45 IRPP[0:1]FFERRHD[0:3]
IRP Protocol Fatal FERR Header Log.
Header log stores the IIO data path header information of the associated IRP Protocol
error. The header indicates where the error is originating from and the address of the
cycle. The header information will be varies according the four error types: Message,
Memory/IO Request, Configure Request and Completion.
The IRP Protocol Fatal FERR Header totally has 128 bits. Refer to the below table for the
mapping between Header and IRPP[0:1]FFERRHD[0:3] registers.
For the Message Type, the IRP Protocol Fatal FERR Header information as below:
