Operating Modes
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 USB to BDM interface):
Page 16
Make sure that the two “ENABLE” jumpers in the “USB TO BDM INTERFACE” section
are inserted;
Make sure that the “POWER SEL” jumper is in the “USB” position;
Make sure that the “VDD” jumper selects the “ENABLE” position;
Connect the host PC to the board through the provided USB cable.
i
Note: all MCUs in the RS08 family 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.
Please note that the BKGD line is shared with the PTA3 line and the
RESET line is shared with the PTA2 line. The user program, therefore,
must not use the PTA3 line when working in host mode.
