Register Description
IF2008/PCIe / IF2008E
10.4 FIFO Volume
Base addr. + 02h (read access)
Bit Function
0 to 14 FIFO data volume (0 to 32767)
15 permanently 0
Fig. 18: FIFO volume
The dataset is transferred automatically into the FIFO data
memory on receipt. By means of a report of the FIFO volume
the FIFO data amount can be calculated. The order and speed
regarding buffering the data received, is similar to the data
stream of the receiving register. In case that the FIFO is not
readout quickly enough, it offers the latest 32768 data sets.
10.5 FIFO Enable Register
Base addr. + 04h (read and write access)
