PERFORMANCE_COUNTER_THRESHOLD_VALUE:
This value is used to compare
against the performance counter. If the performance counter matches this value, an
interrupt is generated if the interrupt bit is enabled. When the source selected is DDB
FIFO status, the threshold value is used to program the value needed to monitor in the
DDB FIFO. No interrupt is generated in this condition.
