        help
            This option is intended to fix the bug that ESP32 is not able to switch to configured
            pullup/pulldown mode in sleep.
            If this option is selected, chip will automatically emulate the behaviour of switching,
            and about 450B of source codes would be placed into IRAM.

        help
            Place GPIO control functions (like intr_disable/set_level) into IRAM,
            so that these functions can be IRAM-safe and able to be called in the other IRAM interrupt context.
