Integrated I/O (IIO) Configuration Registers
14.8.41 GNFERRST, GNNERRST
Global Non-Fatal FERR and NERR Status
14.8.42 IRPP[0:1]ERRST
IRP Protocol Error Status.
This register indicates the error detected by the Coherent Interface.

log:
This field logs the global error status register content when the first fatal
error is reported. This has the same format as the global fatal error status
register (GFERRST).

protocol_parity_error: (DB)
Originally used for detecting parity error on coherent interface, however, no
parity checks exist. So this logs parity errors on data from the IIO switch on
the inbound path.
