Figure 3-10. STARTSCAN Signal Routing
This figure shows that STARTSCAN can be generated from a number of
sources, including the external signals RTSI<0..6> and PFI<0..9> and the
internal signals Sample Interval Counter TC and GPCTR0_OUT.
Many of these timing signals are also available as outputs on the RTSI pins,
as indicated in the RTSI Triggers section, and on the PFI pins, as indicated
in Chapter 4, Connecting Signals.
