            If FreeRTOS detects unexpected behaviour or an unhandled exception, the panic handler is
            invoked. Configure the panic handler's action here.

                Outputs the relevant registers over the serial port and halt the
                processor. Needs a manual reset to restart.

        config ESP_SYSTEM_PANIC_PRINT_REBOOT
            bool "Print registers and reboot"
            help
                Outputs the relevant registers over the serial port and immediately
                reset the processor.

                Just resets the processor without outputting anything

                of the crash.

        help
            To reduce the startup time of an external RTC crystal,
            we bootstrap it with a 32kHz square wave for a fixed number of cycles.
            Setting 0 will disable bootstrapping (if disabled, the crystal may take
            longer to start up or fail to oscillate under some conditions).

            If this value is too high, a faulty crystal may initially start and then fail.
            If this value is too low, an otherwise good crystal may not start.

            To accurately determine if the crystal has started,
            set a larger "Number of cycles for RTC_SLOW_CLK calibration" (about 3000).
