SMC_PMPROT not changing

Hello,

 

I'm using a MKL17Z256VFM4 and I am currently trying to optimize the power consumption of the MCU.

 

I'm finding that when I try to change the value of SMC_PMPROT, either via processor expert or simply writing to the register, I never see the changes. Writing to SMC_PMPROT is done right after reset.

 

All the power management registers stay at their default values and I'm not sure what could be causing the issue.

 

Thanks for the help!

 

Laurent
