4.15. Emergency Download Interface

USB_BOOT is an emergency download interface. Pulling it up to LDO18B_1V8 during power-up will force
the module into emergency download mode. This is an emergency option when failures such as abnormal
start-up or running occur. For the convenient firmware upgrade and debugging in the future, please
reserve this pin.
