fine pitch connector, including the EK-LM3S9B92. The signal direction shown for J1 and J3 applies
when the ICDI is used as the JTAG/SWD debugger and LED D2 (DEBUG ACTIVE) is lit on. In this
case only one of the two connectors J1/J3 should be used.
The ICDI can also be used as a 20-pin to 10-pin adapter for external JTAG debuggers. Note that
the DEBUG ACTIVE LED must be off before connecting any external JTAG debuggers.

Pushbutton
Pushbutton SW1 (RESET) is provided to manually generate the SRSTn signal to the target
device. The SRSTn signal can also be generated under program control.
PWR/UART
The PWR/UART connector J2 connects to the EK-LM3S9B92 evaluation board with a ribbon cable
and provides 5 V power and a virtual communications port connection. This is a 2 x 4 fine pitch
(0.050”) connector, see (Figure 2-8) for signal definition. Signals DBG1/DBG2 are reserved.
