Programmable Registers
21.3.8 PerfMon Total Latency Count Register
The transfer count register defines the total number of latency in cycles during the monitoring
period.
Divide the register value over value of register HW_PERFMON_TRANSFER_COUNT
will give the average latency for each transfer.
Address:
Re-
21.3.9 PerfMon Total Data Count Register
The data count register defines the total number of data transfered in bytes during the
monitoring period.
