I am currently evaluating the i.MX RT1064 and its RT10xx cousins.
I have 4 identical high bandwidth SPI peripherals that I need to control in identical ways (analogous to SIMD), but I need a separate MOSI and MOSI line per each of the four peripheral. I therefore need 9 lines: 1-CLK, 4-MOSI, 4-MISO with a MISO/MOSI pairs for each peripheral (see attached simple schematic). Is it possible to map Quad SPI back to a dumb full-duplex mode? I'm looking to just DMA block of data into memory.
