18 Pin Diagram
The LM3S1621 microcontroller pin diagram is shown below.
Each GPIO signal is identified by its GPIO port unless it defaults to an alternate function on reset.
In this case, the GPIO port name is followed by the default alternate function. To see a complete
list of possible functions for each pin, see Table 19-5 on page 851.
