+ * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
+ * Updated: Fri, 29 Oct 2015 17:19:35 -0700
+ * Status: untested
+ *
+ * Configuration options: not applicable, uses PCI auto config
+ *
+ * The PCI-1720 has 4 isolated 12-bit analog output channels with multiple
+ * output ranges. It also has a BoardID switch to allow differentiating
+ * multiple boards in the system.
+ *
+ * The analog outputs can operate in two modes, immediate and synchronized.
+ * This driver currently does not support the synchronized output mode.
+ *
+ * Jumpers JP1 to JP4 are used to set the current sink ranges for each
+ * analog output channel. In order to use the current sink ranges, the
+ * unipolar 5V range must be used. The voltage output and sink output for
+ * each channel is available on the connector as separate pins.
+ *
+ * Jumper JP5 controls the "hot" reset state of the analog outputs.
+ * Depending on its setting, the analog outputs will either keep the
+ * last settings and output values or reset to the default state after
+ * a "hot" reset. The default state for all channels is uniploar 5V range
+ * and all the output values are 0V. To allow this feature to work, the
+ * analog outputs are not "reset" when the driver attaches.
