21.3.10 PerfMon Maximum Latency Register
The maximum latency register contains the maximum latency in cycles and control signals
for this transaction during the monitoring period.
Address:
21.3.11 PerfMon Debug Register (HW_PERFMON_DEBUG)
The debug register is for internal use only.
Divide the register HW_PERFMON_LATENCY_CYCLE value over this value of this
register will give the average latency for each transfer.
