CC3235MODSF LaunchPad™ Development Kit (LAUNCHCC3235MOD)
2.2.4 Application (or "Backchannel") UART
The board supports a USB-based virtual COM port, using the SimpeLink™ MSP432E401Y Arm
®
MCU.
The LaunchPad is shipped with the UART lines from the CC3235MODSF connected to the UART on the
MSP432E4 MCU. The CC3235MODSF's UART can also be routed to the 20-pin connector for use as a
GPIO or external UART. The selection is performed using jumpers on the board.
Figure 6 shows the UART routed to USB COM port. Ensure that a jumper is also placed on the VBUFFER
header to power the level shifters located on the emulator side of the board. Figure 7 shows the UART
routed to 20-pin header connector.
