As described in the application note, data can be exchanged within a group.
As shown in the figure below, DQ0 and DQ8 are two groups, so they cannot be data bit swapping, is that right?
Sorry, I'll re-describe it to make sure the problem is clear.
Can I connect the QD0 of the MCU to the DQ8 of the DDR, and the QD8 of the MCU to the DQ0 of the DDR?
That is correct. All bit swaps must be within a byte, So you can swap within DQ0-7 or DQ8-15
