The isolation block allows the user to connect or disconnect signals that cross from the XDS110-ET domain into the MSP432P401R target domain. This crossing is shown by the dotted line across the LaunchPad. No other signals cross this domain, so the XDS110-ET can be decoupled from the MSP432P401R target side. -

The XDS110-ET has a configurable baud rate; therefore, it is important that the PC application configures the baud rate to be the same as what is configured on the eUSCI_A0 backchannel UART. MSP432P401R LaunchPad™ Development Kit (MSP ‑ EXP432P401R) SLAU597A – March 2015 – Revised July 2015 Submit Documentation Feedback Copyright ©... - Page 10 The XDS110-ET also supports hardware flow control, if desired. Hardware flow control (CTS and RTS handshaking) allows the target MSP432P401R and the emulator to tell each other to wait before sending more data. At low baud rates and with simple target applications, flow control may not be necessary.

Hardware www.ti.com Measure MSP432 Current Draw To measure the current draw of the MSP432P401R, use the 3V3 jumper on the jumper isolation block. The current measured includes the target device and any current drawn through the BoosterPack headers. To measure ultra-low power, follow these steps: 1. - Page 15 Figure 11 shows all of the functions for which the MSP432P401R device's pins can be configured. This can also be seen in the MSP432P401R data sheet. The BoosterPack side of the dashed line shows the standard. The MSP432P401R function whose color matches the BoosterPack function shows the specific software-configurable function by which the MSP‑EXP432P401R LaunchPad adheres to the standard.
