Access: Read Write
unused
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.
When set to a 1, this bit forces all counters to be reset to 0. This bit is
always read back as 0.
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.
This field is read only. This bit is set to 1 when all statistic counters have
reached their respective overflow warning condition. WRN will be cleared
after one or more of the statistic counters have been cleared.
