PCIe P-Tile avalon RX header address insights

Hi in the P-Tile Avalon in the RX part only lower 6 bits of address is use.
1. Is it a byte address or dword address.
2. If an byte address then how only 6 bits can take byte address greater then 128 bytes in case of 128 MPS and 256 bytes to transfer.
#1st data will be passed with the initial address offset. #2nd data with initial offset+128 byt adress which will eventually go out of 7 bit boundary?

Thank you
Pcie

    >> sorry i do not get your question, may I know what is the current gen speed that you are running ?

    >> where you get the 6 bits address that you acquired from ? is there mentioned in the user guide ? appreciate you can redirect, just to ensure we are looking at the same picture.

    >> may i know specific which rx header that you are looking at ?


    If you are referring to the header width, you may check below
