                different than the OS tick rate of the main core and therefore
                can have different timeout value depending on which core the API

            Set this option to enable printf functionality from LP ROM. This option
            can help reduce the LP core binary size by not linking printf functionality
            from RAM code.

            from the LP ROM.

                Set this option to enable panic handler functionality. If this option is
                enabled then the LP Core will output a panic dump over LP UART,
                similar to what the main core does. Output depends on LP UART already being
                initialized and configured.
                Disabling this option will reduce the LP core binary size by not
                linking in panic handler functionality.
