3.3.5 Local Error Registers
3.3.5.1 IRPP0ERRST—IRP Protocol Error Status Register
This register indicates the error detected by the Coherent Interface.
3.3.5.2 IRPP0ERRCTL—IRP Protocol Error Control Register
This register enables the error status bit setting for a Coherent Interface detected error.
Setting of the bit enables the setting of the corresponding error status bit in IRPPERRST
register. If the bit is cleared, the corresponding error status will not be set.

Description
31:15 RV 0h Reserved
14 RW1CS 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 RW1CS 0b Protocol Queue/Table Overflow or Underflow (DA)
12:11 RV 0h Reserved
10 RW1CS 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
4RW1CS0bCSR access crossing 32-bit boundary (C3)
3RW1CS0b
Write Cache Un-correctable ECC (C2)
A double bit ECC error was detected within the Write Cache.
2RW1CS0b
Protocol Layer Received Poisoned Packet (C1)
A poisoned packet has been received from the Coherent Interface.
1RW1CS0b
Write Cache Correctable ECC (B4)
A single bit ECC error was detected and corrected within the Write Cache.
