2.3.3 Demo #3 Operation - Data Stream Mode

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.
