On-Board Virtual Serial Port
The DEMOQE board has a built-in virtual serial port which may be connected
to the QE processor ’s SCI RXD/TXD. 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.
The DEMOQE Terminal Window Utility, included in the DEMOQE Toolkit on
the accompanying DVD-ROM, is a generic serial port utility which works with
the DEMOQE virtual serial port or actual serial port hardware.

DC9S08QB8 Specific Connections
The labels on the DEMOQE do not necessarily represent actual pin port
function from the MC9S08QB8 microcontroller. In order to take full advantage
of the DEMOQE Base Board resources, MC9S08QB8 signals are mapped to
the DEMOQE Base Board 64-Pin Header as following:
