21.0. Input/Output Ports
Six 10-pin connectors linked to the microcontroller’s I/O ports are provided on the development system. Pins RA0, RA1, RB0, RB1,
RB6 and RB7 are used for programming and therefore are not directly connected to the appropriate 10-pin connector, but via the
programmer’s multiplexer. In addition to these 10-pin connectors, the development system includes screw connectors and pads suitable
for placing additional components. Jumpers next to the PORTA and PORTB ports’ 10-pin connectors enable connection between pull-
up/pull-down resistors and the microcontroller pins.
