Hello @ferqtek
ok, I see. However it is stated here:
When an SPI Host is set to 80 MHz or lower frequencies, routing SPI pins via the GPIO matrix will behave the same compared to routing them via IOMUX.
What SPI bus frequency are you planning to use?
It also states:
If at least one signal is routed through the GPIO matrix, then all signals will be routed through it.
which I read as: if no signal is routed through the GPIO matrix then it is using IOMUX (but I could be wrong about that).
Thanks
Felix
