3.5 External Interface, XINTF
This section gives a top-level view of the external interface (XINTF) that is implemented on the F2812
device.
The external interface is a non-multiplexed asynchronous bus, similar to the C240x external interface. The
external interface on the F2812 is mapped into five fixed zones shown in Figure 3-3.
Figure 3-3 shows the F2812 XINTF signals.
