K_Timer and RTC Integration

We are using the nRF5340 with Zephyr OS v3.6.99-100befc70c74 and nRF Connect SDK v2.7.0-5cb85570ca43. We have the following questions:

  1. Is our understanding correct that the K_Timer utilizes the RTC and operates in the interrupt handler mode of the RTC?

  2. What is the tick duration when using the K_Timer with RTC?

    when,
    CONFIG_TICKLESS_CAPABLE=y
    CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC=32768
    CONFIG_SYS_CLOCK_TICKS_PER_SEC=32768
    CONFIG_SOC_NRF53_RTC_PRETICK=y
    CONFIG_SOC_NRF53_RTC_PRETICK_IPC_CH_FROM_NET=10
    CONFIG_SOC_NRF53_RTC_PRETICK_IPC_CH_TO_NET=11
  3. Is there a mechanism to generate a software timer that counts the delay without running in the interrupt handler?
