         *     RTSI Board Interface--Configured as an input, each bidirectional
         *     RTSI_BRD pin can drive any of the seven RTSI_TRIGGER pins.
         *     RTSI_BRD<0..1> can also be driven by AI STOP and RTSI_BRD<2..3>
         *     can also be driven by the AI START and SCAN_IN_PROG signals.
         *     These pins provide a mechanism for additional board-level signals
         *     to be sent on or received from the RTSI bus.
         *   Couple of comments:
         *   - Neither the DAQ-STC nor the MHDDK is clear on what the direction
         *     of the RTSI_BRD pins actually means.  There does not appear to be
         *     any clear indication on what "output" would mean, since the point
         *     of the RTSI_BRD lines is to always drive one of the
         *     RTSI_TRIGGER<0..6> lines.
         *   - The DAQ-STC also indicates that the NI_RTSI_BRD lines can be
         *     driven by any of the RTSI_TRIGGER<0..6> lines.
         *     But, looking at valid device routes, as visually imported from
         *     NI-MAX, there appears to be only one family (so far) that has the
         *     ability to route a signal from one TRIGGER_LINE to another
         *     TRIGGER_LINE: the 653x family of DIO devices.
         *
         * For m-series, the bit layout of this register is
