There are three examples programmed into the DEMO9S08RG60 board. The programs are: 1) Debug monitor 2) Stop3 demo Freescale Semiconductor, Inc... 3) Paced-loop demo The Debug Monitor is the most important program loaded into the MCU residing on the Demo board. In conjunction with software running on a host personal computer (PC), the debug monitor enables users to program FLASH and debug their programs. This Demo requires CodeWarrior to be installed on the development PC. The other demo programs offer examples of some simple uses of the Demo board. The Stop3 Demo illustrates the low-power capability of the MC9S08RG60 microcontroller operating in stop3 mode. The Paced-Loop Demo demonstrates a framework that users can implement in their system to periodically execute user routines. What Do the Demo Programs Do? The Stop3 demo program executes by default at power up if no pushbuttons are held down. This program demonstrates operation of the microcontroller in low power, stop3, mode. The program uses the real time interrupt (RTI) to recover from stop3 mode. In stop3 mode, clocks are halted and only IRQ, KBI, LVI, and RTI interrupts can occur. For this reason when using the serial debugger, you can not trace through the demo code once you have reached a stop instruction. If you are using the serial debugger, you press the go button in the debugger program, and test 1 is entered (No user switches pressed) you will no longer be able to halt or trace the demo code. This is because there are no clocks to the serial communications module. With the Stop3 Demo running, LED1 will flash approximately twice a second. While the LED is off, the MCU is in low-power, stop3 mode, and will remain in stop3 mode until the next RTI. RTI is generated periodically by an MCU timer. During Stop3 Demo execution, press and hold SW1 for at least 0.5sec. LED1 will turn-on for approximately 3 seconds. Pressing SW2 for at least 0.5sec will cause LED2 to turn-on. The Software-paced loop demo program executes when SW2 is held down at power-up. The software-paced loop program blinks LED1 and LED2. LED1 will blink on and off every second. LED2 will blink on and off every two seconds. Both LEDs blink at a 50% duty cycle. 6 On This Product, For More Information Go to: www.freescale.com D E M O 9 0 8 G B 6 0 Freescale Semiconductor, Inc. 0 2 / 0 6 / 0 4 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. Freescale Semiconductor, Inc... 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. Table 1: Demo Program Selection Switch (SWx) Demo Program Executed No Switch held down SW2 SW1 Stop3 Demo Paced-Loop Demo Debug Monitor NOTES: 1) When power is applied to the Demo board, if none of the switches is held down, the lowpower, stop3, demo program executes by default. 7 On This Product, For More Information Go to: www.freescale.com D E M O 9 0 8 G B 6 0 Freescale Semiconductor, Inc. 0 2 / 0 6 / 0 4 2) When power is applied to the Demo board and SW2 is held down, the paced-loop demo program executes. 3) When power is applied to the Demo board and SW1 is held down, the serial Debug Monitor program will execute. CodeWarrior must be running on the host PC to use the monitor program. Connect a straight through DB-9 serial cable between COM port on the PC and SCI1 on the Demo board to allow communications.

COMMUNICATION: The MCU supports a maximum 38.4K bps serial communication rate on the SCI1 interface port. POWER ON or RESET PROMPT: The monitor provides a binary prompt to the Demo board serial SCI1 port. 8 On This Product, For More Information Go to: www.freescale.com D E M O 9 0 8 G B 6 0 Freescale Semiconductor, Inc. 0 2 / 0 6 / 0 4 COMMANDS: No user commands can be applied via the keyboard with software such as HyperTerminal or AxIDE. The monitor commands are binary and not compatible with keyboard (ASCII) entry or display. Host based software should interface with the monitor on the serial communication port to provide development support. Freescale Semiconductor, Inc... INTERRUPT SERVICE SUPPORT: The monitor enables automatic hardware vector relocation in the MC9S08RG60 so user interrupt vectors appear from 0xFBCC to 0xFBFF. Users do not have access to the SCI1, SWI, and RESET vectors while the monitor is operating. Programming the user Reset vector (0XFBFE:0xFBFF) will cause the monitor to execute the user program on Reset. See the AN2140 application note for user interrupt application. DEMO9S08RG60 Board Operation The DEMO9S08RG60 board provides input and output features to assist in application development. Access to MCU ports is available through module the MCU_PORT connector. The MCU_PORT connector may be used to interface power to the module as well as RS-232 communications signals. Care must be exercised when using the MCU_PORT to power the module, as only regulated +3.3V should be applied to this connection. Five option jumpers and 3 cut-traces setup module operation. Enabling an associated option requires installing a jumper, or shunt, across the appropriate header pins. Removing the shunt will disable the associated option. An option that is enabled by a cut-trace can be disabled by removing the circuit trace between the cut-trace component pads. Install a suitably sized 0ohm resistor or piece of wire to re-enable the option. POWER SUPPLY Input power may be applied by external connection to a 2 position terminal block and 3.3V regulator or directly from connector J1. The input supply is selected by the PWR_SEL option. PWR_SEL Jumper The PWR_SEL jumper selects the source of power input to the DEMO9S08RG60 module. The module may be powered from connections to a 2 position, screw type, terminal block or from 40-pin MCU connector. Power input to the terminal block must be DC voltage between +5V and +12V. Power input on the MCU connector must be regulated voltage between +3.0VDC and +3.3VDC. Use of the MCU_PORT connector input allows use of batteries to power the module. Damage may occur if the MCU_PORT power input pins are over-driven. Refer to the table below to determine correct PWR_SEL jumper setting. 9 On This Product, For More Information Go to: www.freescale.com Freescale Semiconductor, Inc.

The PWR terminal block allows external voltage to be applied to the module. Input voltage should be limited to between +5VDC and +12VDC. Input voltage of +9VDC is typical. The terminal block is a screw type connector that will accept a maximum 16 AWG wire. MCU_PORT 2 Position, Screw Type Terminal Block PWR Connector Input MCU Connector Power may be applied to the board through the MCU_PORT connector pins J1-1 and J1-2. Use of this option requires a regulated voltage input limited to +3.3VDC (+/- 5%). Care should be exercised not to over-drive this input. Reset Switch The RESET switch provides a method to apply an asynchronous reset to the module. Pressing the RESET switch applies a low voltage level to the PTD1/RESET* input. A resistor tied to the high voltage rail will prevent spurious RESET input to the MCU. Crystal Oscillator Crystal oscillator, Y1, provides a 16.0 MHz base operating frequency to the MCU. This provides an 8.0 MHz internal operating frequency. The HCS08 uses dedicated oscillator inputs. This crystal input is not routed to the MCU Port connector 10 On This Product, For More Information Go to: www.freescale.com Freescale Semiconductor, Inc. D E M O 9 0 8 G B 6 0 0 2 / 0 6 / 0 4 Communications Freescale Semiconductor, Inc... The DEMO9S08RG60 module provides a single SCI communications port. This port is connected to the MCU_PORT and to the SCI1 connector. An RS-232 translator (U2) has been provided between the SCI1 connector and the MCU. Communication signals applied to the MCU-PORT connector must be directly compatible with the HCS08 device; no translation support is provided through this path. As added development support, handshake signals RTS and CTS are available at the output of U2. These signals are routed to vias located behind the SCI1 connector. RTS has been biased properly to support 2-wire RS-232 communications. Use of the MCU_PORT interface for RS-232 services requires disabling the on-board RS-232 translator. This is accomplished by opening cut-traces CT1, CT2, and CT3. Simply remove the circuit trace between cut-trace pads to open the circuit. To restore the circuit, install a suitably sized 0-ohm resistor or a short piece of wire across the cut-trace pads. See Cut-Trace Setting above for details.
