-Driver: das16
-Description: DAS16 compatible boards
-Author: Sam Moore, Warren Jasper, ds, Chris Baugher, Frank Hess, Roman Fietze
-Devices: [Keithley Metrabyte] DAS-16 (das-16), DAS-16G (das-16g),
- DAS-16F (das-16f), DAS-1201 (das-1201), DAS-1202 (das-1202),
- DAS-1401 (das-1401), DAS-1402 (das-1402), DAS-1601 (das-1601),

- CIO-DAS1602/16 (cio-das1602/16), CIO-DAS16/330 (cio-das16/330)
-Status: works
-Updated: 2003-10-12
-
-A rewrite of the das16 and das1600 drivers.
-Options:
- [0] - base io address
- [1] - irq (does nothing, irq is not used anymore)
- [2] - dma (optional, required for comedi_command support)
- [3] - master clock speed in MHz (optional, 1 or 10, ignored if
- board can probe clock, defaults to 1)
- [4] - analog input range lowest voltage in microvolts (optional,
- only useful if your board does not have software
- programmable gain)
- [5] - analog input range highest voltage in microvolts (optional,
- only useful if board does not have software programmable
- gain)
- [6] - analog output range lowest voltage in microvolts (optional)
- [7] - analog output range highest voltage in microvolts (optional)
- [8] - use timer mode for DMA. Timer mode is needed e.g. for
- buggy DMA controllers in NS CS5530A (Geode Companion), and for
- 'jr' cards that lack a hardware fifo. This option is no
- longer needed, since timer mode is _always_ used.
-
-Passing a zero for an option is the same as leaving it unspecified.
