    The pin out is shown in Table 6. Pin 6 (Reset) is the active-low reset input. The EB-N701 always requires a reset at power-up, or it will not start properly. An optional onboard reset circuit can be provided. A reset forces the EB-N701 processor to reboot, but will not influence other parameters such as hot or cold start.
  • Page 14: Eb-N701 Debug Interface

    A dedicated pin out (in form of test points) is provided on the board to give the possibility to connect the EB-N701 debug unit. The debug port is intended to be used only during the development stage and to download the firmware at factor setup. It is not meant to be used by the customers unless they want to develop or modify the SW of the EB-N701 module.
