4.3 Programming Cable
The RCM3700 is automatically in program mode when the PROG connector on the programming cable is attached, and is automatically in run mode when no programming cable
is attached.
The DIAG connector of the programming cable may be used on header J2 of the RCM3700
Prototyping Board with the RCM3700 operating in the run mode. This allows the programming port to be used as a regular serial port.
