Dual External Flash with QSPI Interface

[mstanisz]

Hi,

I would like to connect two external SPI flashes to the QSPI interface on my nRF52840.  I see that there's only a single CSN pin that can be configured.  Is it possible use a second IO as a CSN for the second flash or does the QSPI interface only work with a single device?

Thanks,

Matt

Hi Matt

No, it will not be possible to use more than one GPIO as a CSN pin for the QSPI peripheral.
