The ROM code is not executed if :cpp:member:`ulp_lp_core_cfg_t::skip_lp_rom_boot` is set to true. This is useful when you need the ULP to wake-up as quickly as possible and the extra overhead of initializing and printing is unwanted.
In addition to the boot-up code mentioned above the ROM code also provides the following functions and interfaces:
In addition to the boot-up code mentioned above, the ROM code also provides the following functions and interfaces:
* :component_file:`ROM.ld Interface <esp_rom/esp32p4/ld/esp32p4lp.rom.ld>`
* :component_file:`newlib.ld Interface <esp_rom/esp32p4/ld/esp32p4lp.rom.newlib.ld>`

* :component_file:`newlib.ld Interface <esp_rom/{IDF_TARGET_PATH_NAME}/ld/{IDF_TARGET_PATH_NAME}lp.rom.newlib.ld>`
Since these functions are already present in LP-ROM no matter what, using these in your program allows you to reduce the RAM footprint of your ULP application.
