case about nRF52840 qspi

[peter.min]

Hi,

1. Does nRF52840 CKAA WLCSP support QSPI 32MHz?

2. What should qSPI 32MHz measured CLK waveform look like?

3. Is there a 32M QSPI CLK sample diagram actually measured?

4. What are the time requirements for rising edge and falling edge of CLK?

5. I don't find relevant requirements on NRF52840_PS_V1.1, do you have corresponding requirements on QSPI 32MHz waveform data?

Thank you for all your assistance.
Kind regards,
Peter.Min

Yes.

You can find some information and waveforms in the Product Specification:
