Note: Software configuration commands determine P1 digital I/O pin functions. Actual shunt-jumper placement is required to provide
±15 VDC to expansion cards or disconnect internal DAC references to allow externally selected DAC references. Digital I/O cannot
be used with DBKs. “/” indicates the pin can be used for either function but not both at the same time.
