Figure 3-19 in Chapter 3, Theory of Operation, diagrams the
AT-MIO-16X RTSI switch connections.
The AT-MIO-16X board has a total of nine signals connected to the
seven A-side pins of the RTSI crossbar switch. These same signals also
appear at the AT-MIO-16X I/O connector. As shown in Table 5-2, two
AT-MIO-16X signals are connected to pin A2, and two signals are
connected to pin A4. The routing of these signals is further controlled
by the bits A4DRV, A4RCV, A2DRV, and A2RCV in Command
Register 2.
• To drive the RTSI switch pin A2 with the signal OUT2, set the
A2DRV bit in Command Register 2. Otherwise, clear the
A2DRV bit.
• To drive the signal GATE1 from pin A2 of the RTSI switch, set
the A2RCV bit in Command Register 2. Otherwise, clear the
A2RCV bit.
