    Hi Dustin,

    They can use an MCU to communicate with the BQ78350. This is a common approach used in many applications.
    I'm not sure what you mean about modifying the bq78350 firmware. The firmware instruction code cannot be modified. If they want to update to a different version of the published firmware or if they want to write the data flash in production, they can use the EV2400 with BQStudio or BQ-Hi-Production (I can share this tool with you if needed).
    The Reset command is described in section 17.2.33 of the TRM.

    Best regards,
    Matt
