/* The time base for the run time stats is generated by a 16 bit timer. Each | |
time the timer overflows ulStatsOverflowCount is incremented. Therefore, | |

bytes are given by ulStatsOverflowCount and the least significant two bytes are | |
given by the current timer counter value. Care must be taken with data | |
consistency when combining the two in case a timer overflow occurs as the | |
value is being read. */ | |
