5.3 Host Mode
In host mode the program execution is controlled by the host PC through the “USB” connector.
You can use the PC to debug the application by, for example, executing the program step by
step and watching how the microcontroller registers vary, using the provided CodeWarrior
Development Studio.
To work in host mode (using the built-in microDART interface):

Make sure that the board is powered on;
Make sure that the “RESET” and “BKGD” jumpers in the “microDART INTERFACE”
section are inserted;
Connect the host PC to the board through the provided USB cable.

Note: the MC9S08QE128 and MCF51QE128 devices contain a single-
wire background debug interface which supports in-circuit programming of
on-chip non-volatile memory. This system does not interfere with normal
application resources. It does not use any user memory or locations in the
memory map. The Background Debug Module (also known as
Background Debug Controller, BDC) uses a single-wire communication
interface (via the BKGD line) to allow non-intrusive access to target
system memory and registers.
