3.4 Device Emulation Registers
These registers are used to control the protection mode of the C28x CPU and to monitor some critical
device signals. The registers are defined in
Table 3-7 .

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.
