nRF5340 QSPI Pin Configuration

[spredn2]

The product specification states that "only the dedicated QSPI pins shall be used." Is this a recommendation or a requirement? I would like to configure a different pin in the QSPI peripheral for CSN.

Hi,

It is a requirement to guarantee that the QSPI works as intended. It is possible to configure the QSPI to other pins, but they might not perform well at high frequencies or cause a lot of interference with the radio/other systems in this part.

Let me know if this answers your question!

Kind regards,
Andreas
