7189 - CertusPro-NX/PCI Express: What is the AHB slave interface Endianness completion format for PCIe x4?
Description:

- Bytes 8-11 here illustrate Memory TLP, which contains Address field. It could be other fields, depending on the TLP type.
- Bytes 12-15 here show the payload field for 3-DW header TLP. It could be a 4th-DW header field, or it does not exist (e.g. a 3-DW Memory Read TLP). If it is a 4th-DW header field, it should follow header (e.g. bytes 8-11) endianness.
