The Debug Monitor program is executed when SW1 is held down at power-up. The serial
debugger, when used with a host PC and CodeWarrior software, enables a user to erase
device FLASH memory, program FLASH memory, load application programs, and debug the
application programs. The debug monitor dedicates SCI1 as its connection to the host PC and
does not use the traditional background debug mode, thus eliminating the necessity for a
background debug mode cable. Free software is available for execution on a PC as an
interface to the monitor. Refer to application note AN2140 for a full explanation for using the
debugger.
Executing the Demo Programs
Before you can run the demo programs, configuration jumpers must be installed on the Demo
board. To run the Demo programs install all 4 User Interface jumpers (User-1 through User-4).
Install the PWR_SEL jumper as shown above to select the applied voltage source.
If neither push-button switch is depressed during RESET or at power-on, the Stop3 Demo
executes automatically. As noted above, this demo highlights the low-power feature of the
MC9S08RG60 MCU.
To execute the Paced Loop Demo, press and hold SW2 then press and release the RESET
switch.
To use the monitor program, connect a straight through DB-9 serial cable between the COM
port on the PC and the SCI1 connector on the Demo board. CodeWarrior software must be
installed on the host PC to support the serial monitor.
Selecting the Demo Programs
Pushbutton switches are used to select between installed demo programs. The switches are
read at the rising edge of RESET. Hold down the chosen pushbutton while applying power or
while pressing the RESET switch. The actions of the switches are shown in the table below.
NOTES:
1) When power is applied to the Demo board, if none of the switches is held down, the low-
power, stop3, demo program executes by default.
