1100 	 *   According to DAQ-STC:
1101 	 *     RTSI Board Interface--Configured as an input, each bidirectional
1102 	 *     RTSI_BRD pin can drive any of the seven RTSI_TRIGGER pins.
1103 	 *     RTSI_BRD<0..1> can also be driven by AI STOP and RTSI_BRD<2..3>
1104 	 *     can also be driven by the AI START and SCAN_IN_PROG signals.
1105 	 *     These pins provide a mechanism for additional board-level signals
1106 	 *     to be sent on or received from the RTSI bus.
1107 	 *   Couple of comments:
1108 	 *   - Neither the DAQ-STC nor the MHDDK is clear on what the direction
1109 	 *     of the RTSI_BRD pins actually means.  There does not appear to be
1110 	 *     any clear indication on what "output" would mean, since the point
1111 	 *     of the RTSI_BRD lines is to always drive one of the
1112 	 *     RTSI_TRIGGER<0..6> lines.
1113 	 *   - The DAQ-STC also indicates that the NI_RTSI_BRD lines can be
1114 	 *     driven by any of the RTSI_TRIGGER<0..6> lines.
1115 	 *     But, looking at valid device routes, as visually imported from
1116 	 *     NI-MAX, there appears to be only one family (so far) that has the
1117 	 *     ability to route a signal from one TRIGGER_LINE to another
1118 	 *     TRIGGER_LINE: the 653x family of DIO devices.
1119 	 *
1120 	 * For m-series, the bit layout of this register is
1121 	 * (docs: mhddk/nimseries/ChipObjects/tMSeries.{h,ipp}):
1122 	 *   bits  0:3  --  NI_RTSI_BRD(0) source selection

1125 	 *   bits 12:15 --  NI_RTSI_BRD(3) source selection
1126 	 *   Note:  The m-series does not have any option to change direction of
