Hi I.mx7 experts, I saw that the EPDC controller of I.MX7 dual process has D0-D15, totally 16 pins for E-ink display. However, E-ink display only need 8 pins for data transfer, usually D0-D7. So, what is the usage of D8-D15 pins for EPDC controller? Can it use D8-D15 to transfer data to second e-ink display? Please advise.
