CH1 = IN-)   |\n+----------------+------------------------------+\n| CH1            | DF0 (CH0 = IN-; CH1 = IN+)   |\n+----------------+------------------------------+\n| CH2            | DF0 (CH2 = IN+; CH3 = IN-)   |\n+----------------+------------------------------+\n| CH3            | DF0 (CH2 = IN-; CH3 = IN+)   |\n+----------------+------------------------------+\n| CH4            | DF0 (CH4 = IN+; CH5 = IN-)   |\n+----------------+------------------------------+\n| CH5            | DF0 (CH4 = IN-; CH5 = IN+)   |\n+----------------+------------------------------+\n| CH6            | DF0 (CH6 = IN+; CH7 = IN-)   |\n+----------------+------------------------------+\n| CH7            | DF0 (CH6 = IN-; CH7 = IN+)   |\n+----------------+------------------------------+\n\nUse the table above as the operation mode when calling\n``MCP3008.read(modes)`` or setting the ``MCP3008.fixed(modes)`` mode.\n(e.g. ``MCP3008.read([mcp3008.CH0, mcp3008.DF1])``)\n\n\n",
