Interfacing to the EVB
An array of accessible I/O signals makes it easy to interface the EVB to external circuits. All
LM3S1968 I/O lines (except those with both JTAG and SWD functions) are brought out to 0.1”
pitch pads. For quick reference, silk-screened labels on the PCB show primary pin functions.
Table B-2 on page 28 has a complete list of I/O signals as well as recommended connectors.
Most LM3S1968 I/O signals are +5-V tolerant. Refer to the LM3S1968 data sheet for detailed
electrical specifications.
Using the In-Circuit Debugger Interface
The Stellaris LM3S1968 Evaluation Kit can operate as an In-Circuit Debugger Interface (ICDI).
ICDI acts as a USB to the JTAG/SWD adaptor, allowing debugging of any external target board
that uses a Stellaris microcontroller. See “Debugging Modes” on page 12 for a description of how
to enter Debug Out mode.
