4.2.8 Statistics
A significant portion of the initialization buffer is reserved for statistical information collected by the
MK50H27. When a statistic is updated, the MK50H27 will read the appropriate statistic, increment it,
and then write it back out to memory. These statistics are intended for the use of the Host CPU for
statistical analysis. The MK50H27 will only increment these counters; it is up to the user to clear and
preset these counters. The statistics collected are:
