Counter Data (CNTRDATA_1) – Offset 1208
Each CNTRDATA register is an N-bit counter that is used to count occurrences of configured events, where N is the value of the Counter Width field in PERFCAP. Behavior of software reads and writes to these registers are described in #671116 section 6.3. Once written, the counter continues to increment from the written value. A freeze operation causes the counter to stop accumulating further events and to retain its value at the time of freeze. An unfreeze operation allows the counter to resume counting subsequent events.
