These boards are almost identical to the AT-MIO E series, except that
they use the PCI bus instead of ISA (i.e., AT).  See the notes for
the ni_atmio.o driver for additional information about these boards.

Autocalibration is supported on many of the devices, using the
comedi_calibrate (or comedi_soft_calibrate for m-series) utility.
M-Series boards do analog input and analog output calibration entirely
in software. The software calibration corrects
the analog input for offset, gain and
nonlinearity.  The analog outputs are corrected for offset and gain.
See the comedilib documentation on comedi_get_softcal_converter() for
more information.

By default, the driver uses DMA to transfer analog input data to
memory.  When DMA is enabled, not all triggering features are
supported.

Digital I/O may not work on 673x.

Note that the PCI-6143 is a simultaineous sampling device with 8 convertors.
With this board all of the convertors perform one simultaineous sample during
a scan interval. The period for a scan is used for the convert time in a
Comedi cmd. The convert trigger source is normally set to TRIG_NOW by default.

The RTSI trigger bus is supported on these cards on
subdevice 10. See the comedilib documentation for details.

Information (number of channels, bits, etc.) for some devices may be
incorrect.  Please check this and submit a bug if there are problems
for your device.

SCXI is probably broken for m-series boards.

Bugs:
 - When DMA is enabled, COMEDI_EV_CONVERT does
   not work correctly.

	ISSUES:

	need to deal with external reference for DAC, and other DAC
	properties in board properties

	deal with at-mio-16de-10 revision D to N changes, etc.

	need to add other CALDAC type

	need to slow down DAC loading.  I don't trust NI's claim that
	two writes to the PCI bus slows IO enough.  I would prefer to
	use udelay().  Timing specs: (clock)
		AD8522		30ns
		DAC8043		120ns
		DAC8800		60ns
