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.
