CONNECTIVITY
INPUT/OUTPUT GROUP
EVERYTHING IS GROUPED TOGETHER
There are eight PORTs on the PICPLC16 v7a development board, labeled from PORTA
to PORTH. The PORTs are located along the right side of the board, each containing a
an eight-pole DIP switch, and a single 2x5 pin header with the standard 2.54mm pitch.
The PORTs are labeled according to the MCU PORT they are routed to, and they add so
much to the connectivity potential of the There are eight PORTs on the PICPLC16 v7a

CONNECTIVITY
TRI-STATE DIP SWITCHES
Tri-state DIP switches are used to enable 4K7 pull-up or pull-down resistor on
any desired port pin. Each of these switches has three states:

1.
MIDDLE POSITION
disables
both pull-up and pull-down feature
from the PORT pin
2.
UP POSITION
connects the
resistor in pull-up state to the selected
pin
3.
DOWN POSITION
connects
the resistor in pull-down state to the
selected PORT pin.
I/O pins of MCU are internally grouped as PORTs. The same grouping concept is kept throughout the development board as
well, offering a clean and organized user interface.
