Should we use DB00..DB05 or DB02..DB07 pins for 18 bit parallel LCD interface?

Dear Group


We are designing a project hardware with i.mx6. To reduce the cost, we need to use parallel LCD data bus interface. As far as I know, LCD DB02 to DB07 bits are used for 6 bits parallel interface. But when I checked the i.mx6 dual core schematic (sch-27767_A_X3_ALT.pdf) I see that data bus is connected sequentially from DB00 to DB17.

Is two bit shift problem is solved in i.mx6, and can we connect the LCD data bus as pin to pin as in sch-27767_A_X3_ALT.pdf, or is it depend on type of the LCD used?


Best regards.
