 * Driver: adq12b
 * Description: Driver for MicroAxial ADQ12-B data acquisition and control card
 * Devices: [MicroAxial] ADQ12-B (adq12b)
 * Author: jeremy theler <[email protected]>
 * Updated: Thu, 21 Feb 2008 02:56:27 -0300
 * Status: works
 *
 * Configuration options:
 *   [0] - I/O base address (set with hardware jumpers)
 *		address		jumper JADR
 *		0x300		1 (factory default)
 *		0x320		2
 *		0x340		3
 *		0x360		4
 *		0x380		5
 *		0x3A0		6
 *   [1] - Analog Input unipolar/bipolar selection
 *		selection	option	JUB
 *		bipolar		0	2-3 (factory default)
 *		unipolar	1	1-2
 *   [2] - Analog Input single-ended/differential selection
 *		selection	option	JCHA	JCHB
 *		single-ended	0	1-2	1-2 (factory default)
 *		differential	1	2-3	2-3
 *
 * Driver for the acquisition card ADQ12-B (without any add-on).
 *
 * - Analog input is subdevice 0 (16 channels single-ended or 8 differential)
 * - Digital input is subdevice 1 (5 channels)
 * - Digital output is subdevice 1 (8 channels)
 * - The PACER is not supported in this version
