Operation
This is a software-only reset.
This operation should only be invoked by calling a function in the FlashBlock library. Device specifications are no
longer guaranteed if this function is directly called by the user’s code .
This function can only be invoked by the device programmer, not by user’s code.
The address is hard coded by algorithm.
User-writeable registers include Main Oscillator Trim (IMO_TR), Internal Low Speed Oscillator Trim (ILO_TR), and
Bandgap Trim (BDG_TR).
