14 ROS-V 0b
Protocol Parity Error (DB)
This bit was originally used for detecting parity error on coherent interface:
however, no parity checks exist. Thus, this bit logs parity errors on data from the
IIO switch on the inbound path.
13 ROS-V 0b Protocol Queue/Table Overflow or Underflow (DA)
12:11 RV 0h Reserved
10 ROS-V 0b
Protocol Layer Received Unexpected Response/Completion (D7)
A completion has been received from the Coherent Interface that was unexpected.
9:5 RV 0h Reserved
4ROS-V0bCSR Access Crossing 32-bit Boundary (C3)
3ROS-V0b
Write Cache Un-correctable ECC (C2)
A double bit ECC error was detected within the Write Cache.
2ROS-V0b
Protocol Layer Received Poisoned Packet (C1)
A poisoned packet has been received from the Coherent Interface.
1ROS-V0b
Write Cache Correctable ECC (B4)
A single bit ECC error was detected and corrected within the Write Cache.
