Rising/Falling Threshold
A rising/falling threshold tracks whether an element is on the desired side of a boundary. It includes
an upper and lower boundary, and the buffer zones are always zero. Events can be selected for
transitions between the boundaries. Rising/falling thresholds are typically used for rate based
counters. Rate based counters are all counters with a time base set to something other than “none”,
this includes the TX Perf and RX Perf counters.
