There are a total of 13 internal timing signals that you can externally control
from the 10 PFI signals on the DAQPad-TB-52. The source for each of
these signals is software selectable from any of the PFIs when you want
external control. This flexible routing scheme reduces the need to change
the physical wiring to the DAQPad-TB-52 for different applications.
You can individually enable each of the PFI signals to output a specific
internal timing signal. For example, if you need the CONVERT* signal as
an output on the DAQPad-TB-52, software can turn on the output driver for
the PFI2/CONVERT* signal. You must be careful not to drive a PFI signal
externally when it is configured as an output.
As an input, you can individually configure each PFI for edge or level
detection and for polarity selection as well. You can use the polarity
selection for any of the 13 timing signals, but using the edge or level
detection depends upon the particular timing signal being controlled.
The detection requirements for each timing signal are listed within the
section that discusses that individual signal.
