nRF52840 QSPI issue

[Oleg]

hello dear Engineers!

I Prepare PCB to produce, so have some question about QSPI pins.

According to the "52.10 Registers" , it is possible to Assign any pins to QSPI (PSEL.xxx)

BUT! According to the "Table 2: QIAA pin assignments" , QSPI the interface linked to the FIXED hi-freq RF pins.

Please, explain more information , how should I do.

Thanks you!

I don't see that in table 2 of the spec I'm looking at. QSPI can be on any pins you like, that table does have a few recommendations as to which pins you might choose but they are only that. I don't see QSPI fixed to anything and if it was it wouldn't be the RF pins. What exactly are you looking at?
