Hi Teams

How long does it take for SPI to communicate normally after I execute the soft reset request?

Because I need to consider in software design the timing of the next SPI communication after soft reset.

Hi Lingzhi,

A soft reset won't take very long as all of the digital core remains powered. To be safe the system should still wait the tMODE_SLP_STBY time (100us) to ensure that the core as adequate time to fully reset before the next SPI command is sent.

Let me know if you have any more questions.
