19.0. Input/Output Ports
Along the right side of the development system, there are seven 10-pin connectors which are connected to the microcontroller’s I/O ports.
Some of the connector’s pins are directly connected to the microcontroller pins, whereas some of them are connected using jumpers. DIP
switches SW1-SW5 enable each connector pin to be connected to one pull-up/pull-down resistor. Whether port pins are to be connected to
a pull-up or pull-down resistor depends on the position of jumpers J1-J5.

down resistor selection
