configTICK_SOURCE --> FREERTOS_USE_RTC and configCPU_CLOCK_HZ --->( SystemCoreClock )

#define configTICK_SOURCE FREERTOS_USE_RTC
#define configCPU_CLOCK_HZ                                                        ( SystemCoreClock )
#define configTICK_RATE_HZ                                                        1024

Hi ,

in the RTOS example, you set 

configTICK_SOURCE as FREERTOS_USE_RTC and configCPU_CLOCK_HZ as( SystemCoreClock ) .Since SystemCoreClock is 64mhz, why did you not set configCPU_CLOCK_HZ as 32768? As I can see in port files everything designed for LF clock, so is configCPU_CLOCK_HZ  just useless?
