In Demo #3, once the MCP2120/22 Developer’s Board # 2 receives a data byte from
the IR interface, the PIC will stream a continuously repeated table (Figure E-1:)
through the IR port.
This demo shows the MCP212X device in an embedded application.
Figure 2-5 shows the system setup for this test, while Figure 2-6 shows the jumper
configuration for the MCP2120/22 board. Lastly, Table 2-6 shows the steps for
Demo #3 operation.
