Simplicity Connector - Silicon Laboratories SLSTK3701A User Manual

4.4 Simplicity Connector

The Simplicity Connector featured on the Starter Kit enables advanced debugging features such as the AEM and the Virtual COM port
to be used towards an external target. The pinout is illustrated in the figure below.
The signal names in the figure and the pin description table are referenced from the board controller. This means that VCOM_TX
should be connected to the RX pin on the external target, VCOM_RX to the target's TX pin, VCOM_CTS to the target's RTS pin and
VCOM_RTS to the target's CTS pin.
Note: Current drawn from the VMCU voltage pin is included in the AEM measurements, while the 3V3 and 5V voltage pins are not. To
monitor the current consumption of an external target with the AEM, put the on-board MCU in its lowest energy mode to minimize its
impact on the measurements.
