J2 Serial Interface Connector
J2 provides a simple connection of the evaluation board to the PC via a dongle cable (provided with the
ADuC812 QuickStart Development System).
J3/J6/J7 (Port0 / Port2 / Port 3)
3 parallel ports (Port0, Port2 and Port3) are brought out to the connectors J4, J5 and J6. The exact pinout
of any of these connectors is shown below with reference to figure 3.
