+ * Notes on the 6110 and 6111:
+ * These boards a slightly different than the rest of the series, since
+ * they have multiple A/D converters.  Register level documentation is
+ * not written down for these boards, other than what is here.  If you
+ * have any questions, ask Tim Ousley.
+ * From the driver side, it is only the configuration memory that is a
+ * little different.
+ * Configuration Memory Low:
+ *   bits 15-9: same
+ *   bit 8: unipolar/bipolar (should be 0 for bipolar)
+ *   bits 0-3: gain.  This is 4 bits instead of 3 for the other boards
+ *       1001 gain=0.1 (+/- 50)

+ *       0 DC coupling
+ *   bits 0-2: channel
