- High-resolution timer
- None
It is recommended to stick to the default setting which provides maximum accuracy. If you want to choose a different timer, configure :ref:`CONFIG_{IDF_TARGET_CFG_PREFIX}_TIME_SYSCALL` in project configuration.

RTC Clock Source
@ -35,7 +44,13 @@ The RTC timer has the following clock sources:
- ``Internal 8.5MHz oscillator, divided by 256 (~33kHz)``. Provides better frequency stability than the ``internal 150kHz RC oscillator`` at the expense of higher (by 5 uA) deep sleep current consumption. It also does not require external components.
The choice depends on your requirements for system time accuracy and power consumption in sleep modes. To modify the RTC clock source, set :ref:`CONFIG_{IDF_TARGET_CFG_PREFIX}_RTC_CLK_SRC` in project configuration.

More details on wiring requirements for the ``External 32kHz crystal`` and ``External 32kHz oscillator at 32K_XP pin`` sources can be found in Section 2.1.4 *Crystal Oscillator* of `Hardware Design Guidelines <https://www.espressif.com/sites/default/files/documentation/esp32_hardware_design_guidelines_en.pdf#page=10>`_.
