Question on KW45 Reset

jictannu — Thu, 01 Feb 2024 02:46:06 GMT

Hi all,

I have a question regarding the reset process for KW45. Does the reset source mentioned in Chapter 22 of the KW45 Reference Manual cause both the cm33 and cm3 cores to reset simultaneously? Specifically, for a software reset, is it only requesting a reset for the cm33 core, without affecting the cm3 core?

Best regards,

jictannu

Hello @jictannu

Hope you are doing well.

Some reset requests can affect the CM3 for specific purposes such as debug or flash loading. Please, take a look at the KW45 Reference Manual, Chapter 53 Radio Platform, Section 53.3.5.6 RFMC > Reset; and Chapter 55 RF Core Mode Controller.

Regards,
Eduardo.
