In Demo #2, the MCP2120/22 Developer’s Board #2 will echo the alpha character
received on the IR interface after changing its case (“a” → “A” and “A” → “a”).
This demo shows the MCP212X device in an embedded application.
Figure 2-3 shows the system setup for this test, while Figure 2-4 shows the jumper
configuration for the MCP2120/22 board. Lastly, Table 2-5 shows the steps for
Demo #2 operation.
