22.0. Input/Output Ports
Along the right side of the development system, there are six 10-pin connectors connected to the microcontroller’s I/O ports. Pins used for
programming are not directly connected to the appropriate 10-pin connectors, but via the programmer’s multiplexer. Owing to DIP switch
SW1-SW6, each connector pin can be connected to one pull-up/pull-down resistor. Whether pins of some port are to be connected to a
pull-up or a pull-down resistor depends on the position of jumpers J1-J6.
