SSD1322 (OLED controller) on Flexbus

I'm trying a way to connect a OLED display with SSD1322 controller to the Flexbus peripheral of a Kinetis K60 microcontroller. This controller can be configured to communicate through a 6800 bus.

If I understood well, during write (from MCU to OLED controlled) operations, the SSD1322 reads data on the falling edge of the signal named E. How can I obtain this falling edge with Flexbus? Here it is the basic write operation of Flexbus peripheral.

During data valid interval, there aren't Flexbus signals that go down (falling edge). I could connect FB_CSn to CS of OLED controller and negated FB_CSn to E of OLED controller, but I will have at the same time a rising edge on chip-select and a falling-edge on E signal, and I think this dosn't work.

Any help?

On IMX 6ULL platform , could we just use the on-chip LCD controller in 8080 mode to control the SSD1322 ?

At the moment I'm not able to make some tests on the board. As soon as I can, I will write my results in the community.

Hello,

Have you seen this AN?

TWR-K60 + TWR-LCD can write and read to similar LCD controller in 6800 mode also.
