%SW30 contains the execution time of the last cycle of the MAST task in ms.

interrupts due to higher priority tasks and processing of terminal requests.

%SW31 contains the maximum execution time of the MAST task (the maximum value of %SW30) measured since the last cold start, expressed in ms.

%SW32 contains the minimum execution time of the MAST task (the minimum value of %SW30) measured since the last cold start, expressed in ms.
