DEMO9RS08KA8 User's Manual
5 Operating Modes
5.1 Overview
The Demonstration Board can work in two modes: “standalone” mode and “host” mode.
5.2 Standalone Mode
In standalone mode, no PC connection is required. The microcontroller is factory programmed
with a sample application.
To run the built-in example:
1. Ensure that all of the “ENABLE” jumpers in the “MCU AND I/O” area are inserted.
2. Ensure that all of the “ENABLE” jumpers in the “SERIAL” area are inserted.
3. Ensure that the “POWER SEL” jumper selects the “UNREG” position.
4. Power on the Demonstration Board through the 12 V DC plug-in power supply.
5. The green “POWER” LED on the board should turn on.
6. Press the “SW0” push-button. Rotate the potentiometer. The “LED0” will blink with a
frequency related to the potentiometer value.
7. Press the “SW1” push-button. The “LED1” will blink with a frequency related to amount
of light hitting the photoresistor.
8. The value of the potentiometer or the light sensor is also sent to the RS-232 port (baud
rate = 9600, data bits = 8, parity = N, stop bits = 1).
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.
Page 15
Operating Modes
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 (BDM) uses a single-wire
communication interface (via the BKGD line) to allow non-intrusive access
to target system memory and registers.
To work in host mode (using the built-in USB to BDM interface):
Make sure that both the “RESET#” and “BKGD” jumpers (in the “USB TO BDM
INTERFACE” area) are inserted.
Make sure that the “POWER SEL” jumper is in the “USB” position.
Connect the host PC to the board through the provided USB cable.
