CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC

Hardware clock cycles per second, 2000000 for ISS

System clock’s h/w timer frequency

Type: int

Help

This option specifies hardware clock.

Help

This option specifies the frequency of the hardware timer used for the
system clock (in Hz). This option is set by the SOC's or board's Kconfig file
and the user should generally avoid modifying it via the menu configuration.

      This option specifies the frequency of the hardware timer used for the
      system clock (in Hz). This option is set by the SOC's or board's Kconfig file
      and the user should generally avoid modifying it via the menu configuration.
