RTSI Triggers
The seven RTSI trigger lines on the RTSI bus provide a very flexible
interconnection scheme for the 6711/6713 device sharing the RTSI bus.
These bidirectional lines can drive any of five timing signals onto the RTSI
bus and can receive any of these timing signals. This signal connection
scheme is shown in Figure 3-4.
