7.1.3

J24 - MCU PORT

Select the MCU_PORT to supply microcontroller VDD. This setting also
allows power to be supplied to the target connected to the MCU_PORT. By
default this jumper is installed.

7.2

Virtual Serial Port

The DEMOEM board has a built-in virtual serial port which may be connected
to the EM processor’s SCI or SCI3 Rx and Tx. This allows certain PC
applications to be able to connect in a serial fashion to the microcontroller
without the actual use of serial port hardware. It can be enabled or disabled
by installing or removing the jumpers of J7 and J8.
