Auto refresh mode

The analog acquisition is initialized and writes the values of the channels
into a storage location on the APCI-3xxx. The PC reads the data
asynchronous to the acquisition.

Analog outputs

There are 4 analog output channels with a resolution of 12-bit and a
precision of 11-bit on the APCI-3110 and APCI-3116.
The analog outputs are updated by 32-bit writing on the I/O addresses. The
status bit (DAC Ready) indicates if the analog outputs are ready for a new
update.
The time ("Time to ready") between the writing on the I/O addresses (DAC
register) and the update of the analog outputs is 5 µs. Further accesses to the
DAC register will not be considered in this period. The time between
writing in the software command and reaching the set value for the analog
outputs is 15 µs (settling time).
