Hi, if the internal MCU (M4) isn't being used can it be held in reset (MCU_RSTz pulled low)? Would this lower power or EMI associated with the M4 or is there a better way?
Thanks

Hello Steven Richardson10
Thank you for the query.
Would this lower power or EMI associated with the M4 or is there a better way?
Can you please elaborate your query including use case

Hello Steven Richardson10,
Please refer below
The M4 has a dedicated LPSC, so the M4 can be powered off instead of being held in reset, it would save all the power.

Hello Steven Richardson10,
For the use case you have stated, using the MCU_RSTz with pulled down configuration is not recommended.
