UART Signals
The board supports a USB-based virtual COM port, which is used on the FTDI device FT2232D. There
are two ports on the FT2232: the first port is dedicated for the emulation (JTAG/SWD) and the second port
is used for the virtual COM port. The UART can also be routed to the 20-pin connector and the selection
is performed using jumpers on the board.

Sense on Power
The CC3200 can be set to operate in three different modes based on the state of the sense-on-power
(SOP) lines. These are pins 21, 34, and 35 on the CC3200 device. The state of the device is described in
.

Usage
Comments
SOP[2:0]
100 = Flash programming
000 = Functional mode + 4-Wire JTAG
001 = Functional mode + 2-Wire JTAG
SOP[2:0] corresponds to J15, J16, and J17 in the LaunchPad kit schematic design.
