UART Device Emulation Module (DEM-UART)

Fig. 12 High-Level Overview of the Device Emulation Module for UART (DEM-UART)

The UART Device Emulation Module connects to the bus of a given CPU on one side, and to the Debug Interconnect on the other. Towards the CPU it behaves like a UART-16550A device, but instead of transmitting information over a UART-Interface it instead passes it to a host PC via the Debug Interconnect.
