I'm qualifying the CFAF240320X0-020T for a product, and going through the various control interface options. There's some data in the datasheet, but most of it I need to go to the (embedded) ST7789V controller datasheet.
The biggest question is the interface mode. Problem: the ST7789V has four lines (IM3, IM2, IM1, IM0) to configure its interface mode, but the CFAF240320X0-020T only has three visible lines, omitting IM3. I tried to figure out whether IM3 was tied high or low, but looking at the available modes in the CFAF240320X0-020T doc I find evidence for both ways.
Question: how do the CFAF240320X0-020T's IM[2:0] pins map to the ST7789V's IM[3:0]?
