15.2 Access Statistics
These statistics are for both reads and writes, and can be used to tune the operating system for optimum
performance.
Every time statistics are viewed, the controller first outputs the time since the statistics were last reset.
However, the statistics can be cleared at any time. This is useful in determining the access pattern for a
particular test or period of time.
