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 3−9.

External Interface, XINTF (2812 Only)

This section gives a top-level view of the external interface (XINTF) that is implemented on the 2812 devices.

The external interface is a non-multiplexed asynchronous bus, similar to the C240x external interface. The

external interface on the 2812 is mapped into five fixed zones shown in Figure 3−5.

Figure 3−5 shows the 2812 XINTF signals.
