Programming with the Low-level API
A DMap holds one data point per configured channel. One copy of the map is
stored on the IOM and another is stored on the host. The IOM updates its
version of the map at the DMAP_RATE specified during initialization, and the
ADCs are clocked at this rate. Calling DqRtDmapRefresh() transfers the latest
input data from the IOM to the host; the data can then be read from the host map
using DqRtDmapReadRawData32(). For more information on RtDMap, see
the "PowerDNx Protocol Manual."
