Typically, initializing and reading the system counter frequency includes setting the system counter frequency using the system register interface, only during the system boot process. The system counter frequency is set by writing the system counter frequency to the CNTFRQ register. Only software executing at the highest exception level implemented can write to CNTFRQ.
