I have gone through the Reference Manual of P3041 PCIe but I am not clear of the following. Could someone help:
- Posted request and non-posted request: For outbound transfers, such as memory write to an external device, which one would the PCIe controller use?
- Outbound transaction size: For example, from the software application, it performs some write into specific area predefined for PCIe outbound transfer (memory write).
How would the PCIe controller know how much data to transfer out each time?
