The settings in
For simple event counting, a non-threshold event is selected in PMLCAn[EVENT] and all other features
are disabled by clearing all register fields except for CE.
For the triggering example any event can be selected in PMLCAn[EVENT]. All other features are disabled
by clearing these register fields except for CE to allow interrupt signalling. If PMLCBn[TRIGONSEL] is
3 and PMLCBn[TRIGOFFSEL] is 5, the counter begins and ends counting based on the conditions in
counters three and five. Furthermore, if PMLCBn[TRIGONCNTL] is 1, the counter begins counting when
PMC3 changes value. According to the setting in PMLCBn[TRIGOFFCNTL], the counter ends counting
when PMC5 overflows. Also, although the register settings for PMC5 is not shown, PMLCAn[CE] for this
counter must be cleared so that interrupt signalling is not enabled and the counter does not freeze when it
overflows.
For threshold counting, a threshold event must be specified in PMLCAn[EVENT]. For this example, the
duration threshold value is scaled by two because PMLCBn[TBMULT] is one. All other features are
disabled by clearing the appropriate fields.
Any non-threshold event can use the burstiness feature. For burstiness counting, values for
PMLCAn[BSIZE,BGRAN,BDIST] and PMLCBn[TBMULT] must be specified.
