KL17 System Register File reset

[laurenthenault]

Hello,

I'm using the system register file to carry some information after a VLLS1 reset. My data is usually kept but will randomly revert back to all 0.

Is there any reason that could force the register to reset except a power-on reset? 

Thanks!

The system register file is only reset during a power-on reset. Please verify that your power supply is stable.
