5. Headers - There are two headers which are connected to the MCP23X17 pins to allow off-board connections. 6. Jumpers - The jumpers are used to isolate the MCP23X17 pins so they can be connected to an off-board circuit. The jumpers are not populated, however, they are shorted by a trace on the bottom of the PCB. - Page 14 MCP23X17 Evaluation Board User’s Guide FIGURE 2-2: MAIN FIRMWARE FLOW Start Init_MCU Init_MCP Check Device Selector Switch Set Serial Mode to MCP23017 or Set Serial Mode to 23017 23S17 MCP23S17?
