Can I configure any GPIO pin as SPIS in nrf52840?

[Yagnik_pokal]

I have seen the datasheet of nRF52840 but I can't find that any GPIO pin used as SPIS. It says that you can configure the pin those whose value is written in the PSEL.MOSI, PSEL.MISO, PSEL.CSN, PSEL.CLK.

Correct me if I am wrong that any GPIO configured as an SPIS.

You could configure any GPIO, but several of them near the antenna pin are restricted to <10kHz frequencies - these should not be used for fast SPIS signals.

Indeed, please take a look at the Pin assignments on the Infocenter to see which ones are recommended to just use as standard drive, low frequency I/O only.

Best regards,
