6.6.3 Trace Memory The trace memory feature allows the PQM to be setup to trigger on various conditions. The
trace memory can record maximum of 36 cycles of data (16 samples per cycle) for all
voltage and current inputs simultaneously. A Total Trace Triggers Counter has been
implemented in the PQM Memory Map at Register 0x0B83. This register will keep a running
total of all valid Trace Memory Triggers from the last time power was applied to the PQM.
The Total Trace Triggers counter will rollover to 0 at 65536. The trace memory feature is
implemented into EnerVista PQM Setup as shown below.
