    Not able to switch Stack pointer to PSP by setting CONTROL[1].

       By default, SP points to MSP on init.


      Steps used:


          1. Set MSP and PSP registers.


          2. Assert SP reset to MSP upon setting.


          3. Set CONTROL[1] to switch SP to PSP.


          4. Asset CONTROL[1] as "high"






          SP still points to MSP. SP is not switching to PSP.






      Are you aware of such behaviour? if yes, Is there any work around?
