Intel IXP400 manual Data Abort with No Parity Error

Intel® IXP400 Software

Access-Layer Components: Parity Error Notifier (IxParityENAcc) API

It is important to note that if an interrupt condition is not cleared then it will result in the parity interrupt being triggered again.

Figure 77–Figure 83 show the process flow that occurs in several data abort and parity error scenarios.
