MIB Counter Strobe
Writing a 1 to this bit location causes the counters in all enabled blocks to increment by 1, providing a
single-step test function. The MIBS bit is always read back as 0. This bit is used for test purposes
only and should be set to 0 for normal counter operation.
Clear all counters
When set to a 1, this bit forces all counters to be reset to 0. This bit is always read back as 0.
Freeze all counters
When set to a 1, this bit forces count values to be frozen such that a read of the statistic block will
represent management statistics at a given instant in time. When set to 0, the counters will increment
normally and may be read individually while counting. While frozen events will not be recorded.
Warning Test Indicator
This field is read only. This bit is set to 1 when statistic counters have reached their respective overflow
warning condition. WRN will be cleared after one or more of the statistic counters have been cleared.
