This operation is used in an application when the
ECU completes the configuration of the MAX9257A/
MAX9258A right after power-up and does not want to
access the MAX9257A/MAX9258A once the video
transmission begins. The following procedure is an
example of one of many possible configurations:
1) Start the program or press the Reset the EVKIT
2) If MAX9257A REM is set to high (JU25 shunt is set

across pins 1-2), press the ECU Wakes Up
MAX9257A button on the ECU Control tab sheet. If
MAX9257A REM is set to low (JU25 shunt is set
across pins 2-3), skip this step.
