            Set the assert behavior / level for HAL component.
            HAL component assert level can be set separately,
            but the level can't exceed the system assertion level.
            e.g. If the system assertion is disabled, then the HAL
            assertion can't be enabled either. If the system assertion
            is enable, then the HAL assertion can still be disabled
            by this Kconfig option.

            Enable this flag to use HAL functions from ROM instead of ESP-IDF.

            If keeping this as "n" in your project, you will have less free IRAM.
            If making this as "y" in your project, you will increase free IRAM,
            but you will lose the possibility to debug this module, and some new
            features will be added and bugs will be fixed in the IDF source
            but cannot be synced to ROM.
