TERMINOLOGY
This development module utilizes option select jumpers to configure default board operation.
Terminology for application of the option jumpers is as follows:
Jumper – a plastic shunt that connects 2 terminals electrically
Jumper on, in, or installed – jumper is a plastic shunt that fits across 2 pins and the shunt is
installed so that the 2 pins are connected with the shunt.
Jumper off, out, or idle – jumper or shunt is installed so that only 1 pin holds the shunt, no 2
pins are connected, or jumper is removed. It is recommended that the jumpers be placed
idle by installing on 1 pin so they will not be lost.
Cut-Trace – a circuit trace connection between component pads. The circuit trace may be
cut using a knife to break the default connection. To reconnect the circuit, simply install a
suitably sized 0-ohm resistor or attach a wire across the pads.
Signal names followed by an asterisk (*) denote active-low signals.

SOFTWARE DEVELOPMENT
Software development requires the use of a compiler or an assembler supporting the HCS08
instruction set and a host PC operating a debug interface. CodeWarrior Development Studio
for Microcontrollers is supplied with this board for application development and debug. Refer
to the supporting CodeWarrior documentation for details on use and capabilities.
DEVELOPMENT SUPPORT
Application development and debug for the target MC9S08SV16 or MC9S08FL16 is supported
through the integrated, Open-Source Background Debug Mode (BDM) interface. An optional
6-pos BDM_PORT header allows connecting an external HCS12/HCS08 BDM cable. The
BDM_PORT header is not installed in default configurations.
Integrated BDM
The DEMO9S08SV16/FL16 board features an integrated Open Source BDM (OSBDM-JM60)
based on the Freescale MC9S08JM60 MCU. The integrated USB BDM supports application
development and debugging via background debug mode. The integrated BDM is fully
supported by CodeWarrior development tools.
The integrated USB BDM provides power and ground to the target board eliminating the need
to power the board externally. Power from the USB BDM is derived from the USB bus. The
integrated USB BDM is designed to sink a maximum of 300mA of current from the USB bus.
Therefore, total current consumption for the target board, and connected circuitry, must not
exceed 300mA. This current limit describes the current supplied by the USB cable to the
BDM circuit, the target board, and any connected circuitry. Excessive current drain will violate
the USB specification causing the bus to disconnect. Damage to the host PC USB hub or the
target board may result.
BDM_PORT Header
A compatible HCS12 BDM cable may also attach to the 6-pin BDM interface header
(BDM_PORT). Figure 2 below shows the pin-out for the BDM_PORT header.
Figure 2: BDM_PORT Header
NOTE: The BDM_PORT header is not installed in default configuration.

POWER
The DEMO9S08SV16/FL16 may be powered from the integrated USB-BDM or from an onboard voltage regulator and external power connector. The desired power source is selected
using the PWR_SEL option header.
For application development and debug, the board may be powered from the integrated USB
BDM. As noted above, total current consumption from this source is limited to 300 mA. A
2.0mm, center-positive, barrel connector (VIN) and on-board regulator supports stand-alone
operation and higher power requirements.
Power may also be applied to connector J1 or the board may be configured to supply power
from connector J1 to external circuitry.
POWER SELECT
Power may be applied to the board through the integrated BDM circuitry, a 2.0mm barrel
connector, or through connector J1. Power selection is achieved using 2 selection headers:
the PWR_SEL option header and the VX_EN option header.
PWR_SEL
The PWR_SEL option header allows the user to select power input either from either an
external power source connected to the VIN connector or from the integrated USB-BDM.
Figure 3 below details the PWR_SEL header connections.

powered from the integrated USB BDM. Damage to the target board or
host PC may result otherwise.

CAUTION:
Do not exceed available current from USB-BDM or on-board regulator
when sourcing power through connector J1 to external circuitry.
U S E R G U I D E
Power from the integrated BDM is drawn from the USB bus and is limited to 300 mA. This
current limit accounts for the total current supplied over the USB cable to the BDM circuit, the
target board, and any connected circuitry. Current drain in excess of value violates the USB
specification and will cause the USB bus to disconnect. This will cause the board to exhibit
power cycling where the board appears to turn off and back on continually. Damage to the
host PC or the target board may result.
Although the on-board regulator can accept voltage input to +25VDC, the applied voltage
should not exceed +12V to prevent the regulator (VR1) from overheating.
VX_EN
The VX_EN option header is a 2-pin jumper that connects or disconnects input J1-1 directly to
the target board voltage rail. J1-3 connects directly to the target board ground plane. Use of
this feature requires a regulated input power source. This power input is decoupled to
minimize noise but is not regulated or protected. Care should be exercised when using this
feature; no protection is applied on this input and damage to the target board may result if
excessive voltage is applied. Also, do not attempt to power the target board through this
connector while also applying power through the USB BDM or the PWR connector; damage to
the board may result.
Power may also be sourced to off-board circuitry through the J1 connector. The current
supplied from the USB bus or the on-board regulator limits current available to external
circuitry. Excessive current drain may damage the target board, the host PC USB hub, or the
on-board regulator. The figure below details the VX_EN header connections.

RESET SWITCH
The RESET switch applies an asynchronous RESET to the MCU. The RESET switch is
connected directly to the RESET* input on the MCU. Pressing the RESET switch applies a
low voltage level to the RESET* input. A pull-up bias resistor allows normal MCU operation.
Shunt capacitance ensures an adequate input pulse width.
Both the MC9S08SV16 and MC9S08FL16 MCU’s apply a multiplexed RESET* input. To use
the RESET switch, the RESET pin must be enabled (SOPT1_RSTPE). Refer to the
MC9S08SV16 or MC9S08FL16 Reference Manual for details on configuring using the RESET*
input.
LOW VOLTAGE RESET
Both the MC9S08SV16 and the MC9S08FL16 apply an internal Low Voltage Detect (LVD)
circuitry. The LVD holds the MCU in reset until applied voltage reaches the appropriate level.
The LVD also protects against under-voltage conditions. Consult the MC9S08SV16 or
MC9S08FL16 Reference Manual for details on LVD operation.
TIMING
Default timing for the DEMO9S08SV16/FL16 is provided by the MC9S08SV16 or
MC9S08FL16 internal timing source which is active out of RESET. External circuitry for an
external 32 kHz XTAL oscillator is provided; however, these components are not populated in
default configuration. Refer to the MC9S08SV16 or MC9S08FL16 Reference Manual for
details on configuring the timing source.
COMMUNICATIONS
Serial communication on the DEMO9S08SV16/FL16 board is supported through an RS-232
physical layer interface and DB-9 connector and through a virtual serial port implemented in
the USB-BDM. The COM_SEL option header selects between the applied serial function.
NOTE: Virtual serial port services are not functional as of the date of this document
COM Port
An RS-232 transceiver provides RS-232 to TTL/CMOS logic level translation between the
COM connector and the MCU. The COM connector is a 9-pin Dsub, right-angle connector. A
ferrite bead on shield ground provides conducted immunity protection. Communication signals
TXD and RXD are routed from the transceiver to the MCU. These signals are also available
on connector J1. Hardware flow control signals RTS and CTS are available on the logic side

USER OPTIONS
The DEMO9S08SV16/FL16 includes various input and output devices to aid application
development and debug. User I/O includes 2 momentary pushbutton switches, 2 green LEDs,
1 potentiometer, 1 temperature sensor, and 1 piezo buzzer. Each device may be enabled or
disabled individually with the USER_EN option header. Each user enable is clearly marked as
to functionality.
Pushbutton Switches
Two push button switches provide momentary, active-low input, for user applications. Pull-ups
internal to the MCU must be enabled to provide error free switch operation. Pushbutton
switches SW1 and SW2 are enabled to the MCU I/O ports by the USER option bank. Table 2
below shows the user jumper settings and MCU connections.
LED Indicators
Two LEDs provide visual output for user applications. Both LEDs are configured for activehigh operation. Table 2 below shows the user jumper settings and MCU connections.
Potentiometer
A 5k ohm, thumb-wheel type, potentiometer at RV1 provides variable resistance input for user
applications. The output is the result of a voltage divider that changes as the thumb-wheel is
turned. The potentiometer is connected between VDD and GND with the center tap providing
the divider output. Table 2 below shows the user jumper settings and MCU connection.
