Figure3-4. CONVERT*Signal Routing
Figure 3-4shows that CONVERT*can be generated from a nu mber of
sources, including the external signals RTSI<0..6>(PCI and PXI buses
only) and PFI<0..9> and the internal signals Sample Interval Counter TC
and GPCTR0_OUT.
OnPCI and PXI devices, many of these timing signals are also available as
outputs on the RTSIpins, as indicated in the RTSI Triggers sectioninthis
chapter,and on the PFI pins, as indicated in Chapter 4, Signal Connections.
Programmable Function Inputs
Ten PFI pinsare available on the device connector as PFI<0..9> and
connectto theinternal signal routing multiplexer of the device for each
timing signal. Software can select any one of the PFI pins as the external
sourcefor a given timing signal. It is i mportant to note that you can use any
oft he PFIpin s as ani nput by any of the timing signals and that multiple
timing signals can use the same PFI simultaneously. This flexible routing
