-    For {IDF_TARGET_NAME}, the High Speed ADC is not available. Hence the non-RF internal entropy source (SAR ADC) is kept enabled by default at the time of application startup. Please note that if the application wants to use ADC for other purposes, it should call :cpp:func:`bootloader_random_disable` before using the ADC and :cpp:func:`bootloader_random_enable` to re-enable the entropy source when the Random Number Generator is needed again.
