    If you start with address 0x5, this means that the data on byte lane 4 in the first transfer will not be valid, so only the "E" of "NE" will be transferred to the slave, with WSTRB=0x20.

    Instead as you want to transfer data "NE", the start address MUST be 0x4, so that byte lanes 4 and 5 are used, with WSTRB=0x30.

    Then the next 3 transfers are all as you show, "WD" with WSTRB=0xC0, "AT" with WSTRB=0x03 and "AA" with WSTRB=0x0C.
