5340 spim + display question

Hi.

I use 5340 + spim 32M (nrfx driver) + ncs 2.0.2 + LVGL library. (display driver ic is RM69090)

I try to communicate display with spim and success work. but refresh is slow to display animation.

so I search and found this section in display driver. 

I used spi4 1wire. i try to use 2wire. i guess that data can send more fast than 1wire.

however in 2wire dcx also use data line. now i just use  nrfx_spim_xfer_dcx function and I couldn't  find any function that dcx send data.

1. Is any function to support 2wire? or I need to write driver myself?

2. is any other way? (use qspi?)

thank you.

Best Regards

Ben
