Programmable Registers
Address:
Re-
21.3.5 PerfMon Latency Threshold Register
The latency threshold Register defines the threshold for AXI transaction latency that can
be enabled to trigger an interrupt to the ARM core when an AXI transaction latency is above
this value.
Address:
Re-
21.3.6 PerfMon AXI Active Cycle Count Register
The active cycle count register counts the number of AXI cycles during which a transaction
is active on AXI bus.
