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.

GETTING STARTED
To get started quickly, please refer to the TWR-S08_QSG Quick Start Guide. This quick start
will illustrate connecting the board to a PC, installing the correct version of CodeWarrior
Development Studio, and running a simple LCD program.
MEMORY MAP
The TWR-S08 is designed to support the complete line of MC9S08LL and MC9S08LH MCU’s.
Refer to the associated target MCU Reference Manual (RM) for details on the target MCU
memory map.
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.
DEVELOPMENT SUPPORT
Application development and debug for the target TWR-S08 board is supported through the
Open-Source Background Debug Mode (OSBDM) interface. The OSBDM is fully supported in
CodeWarrior and provides direct, non-intrusive access to the target device internals. While in
BDM mode, no internal resources are used. Code stepping and break-points are fully
supported.
Connection between a host PC and the target device is provided via a mini-B, USB connector.
The OSBDM is capable of providing power to the target board eliminating the need for external
power. Please note that power supplied by the OSBDM is limited by the USB specification.
When powered through the OSBDM, total current draw, including the OSBDM, TWR-S08
board, and Tower System must remain less that 500mA. Otherwise, the USB bus will cause
the host PC to disconnect the board. Damage to the host PC, target board, or Tower System
may result if this current limit is violated.
NOTE:
The OSBDM will not connect to the TWR-S08 board if the target MCU is in
STOP mode. Wake the target device with an external event then connect to
the target.

CAUTION:
When powered from the USB bus, do not exceed the 500mA maximum
allowable current drain. Damage to the target board or host PC may result
OSBDM Bootloader
The OSBDM is pre-programmed with a bootloader application to allow field updates. The USB
bootloader communicates with a GUI application running on a host PC. The GUI application
enables OSBDM firmware to be updated at any. Option jumper JP400 enables the bootloader
at startup. Option header JP400 is not populated in default configuration. Refer to Freescale
Application Note AN3561 for details on using the GUI application and bootloader. The
application note may be found at www.freescale.com or at www.axman.com/support.
BDM_PORT Header
A compatible HCS12 BDM cable can also be attached to the 6-pin BDM interface header at
J400. This header is not installed in default configurations. This header is provide to allow the
use of alternate programming/debug cables. Refer to the external programming/debug cable
documentation for details on use.
The figure below shows the pin-out for the DEBUG header. This information is included for
completeness.

NOTE: This header is not installed in default configuration.
EXTERNAL BDM CABLE
The integrated BDM allows the user to simply and quickly develop and debug application code.
A BDM port header location is provided for use of an external BDM cable if desired. However,
this BDM port header is not populated in default configurations. Use of an external BDM cable
requires the user to install 6-pin header and to remove a 0-ohm resistor. The user must also
provide power to the board unless power is provided through the external BDM cable. The
P&E Multilink BDM cable used most often with Freescale microprocessors does not provide
power to the target board.

To use an external BDM cable, the user must install a header at location J400. A resistor at
R411 must also be removed to prevent contention between the external BDM cable and the
OSBDM.
To use an external BDM, the user must also apply power to the board. Power may be applied
through the OSBDM or at the COM header. Simply connecting the USB cable to the USB
connector will apply power to the board. The user may also apply power to the COM
connector at J3. Apply +3.3VDC at J3-10 and GND at J3-9. Please note that no over-voltage
or transient protection is applied at this power input.
CAUTION:
Do not apply excessive voltage at input J3-9 and J3-10. Neither over-
voltage nor transient protection is applied at this input.
CAUTION:
Do not apply power to COM connector J3 while also powering the board
through the OSBDM. Damage to the board may result.
The external BDM is now ready for use.
POWER
The TWR-S08 board may be powered from the OSBDM or from the Tower System. A
190mAH battery holder is applied for battery-powered operation. The USB current limit must
be observed while using the USB connection from the host PC to supply power to the target
board. Damage to the target board, Tower System, or host PC may otherwise occur.
POWER SELECT
Option headers V_SEL and VDD_EN select the source of input power to the target board.
When powered from the Tower System, the OSBDM voltage output is disabled.
V_SEL
The V_SEL option header allows the user to select power input either the on-board regulator
or the battery holder. The on-board regulator is supplied from the OSBDM voltage output.
Figure 2 below shows the PWR_SEL header settings.

Power from the integrated BDM is drawn from the USB bus and is limited to 500 mA total.
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 500 mA violates the
USB specification and causes the USB bus to disconnect the offending device. This may
cause the board to exhibit power cycling where the board appears to turn on then off
continually. In this case, LED400 will flash on and off. If this condition is allowed to persist,
damage to the host PC or the target board result.
The on-board voltage regulator (VR1) creates the +3.3V rails used by the target MCU from the
+5V input provided by the OSBDM.
The battery holder at BATT accepts a 3.3V, 23mm, 190mAH lithium, coin-cell battery, PN CR-
2325.
VDD_EN
The VDD_EN option header enables and disables VDD to the target board peripherals. Power
to the MCU is unaffected by this option jumper. Removing this option jumper, along with
others, allows the user to take accurate MCU current measurements. The figure below shows
the VDD_EN option jumper 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.

LOW VOLTAGE RESET
The target MCU applies an internal Low Voltage Detect (LVD) circuit. The LVD holds the MCU
in reset until applied voltage reaches an appropriate level. The LVD also protect against
under-voltage conditions. Consult the target device RM for details on LVD operation.
TIMING
The TWR-S08 uses the MC9S08LL or MC9S08LH internal timing source by default. An
external 32 kHz XTAL oscillator, configured for low-power operation, is also provided. Consult
the target device RM for details on configuring the selected timing source.
COMMUNICATIONS
The TWR-S08 board supports serial communications through an on-board, low-voltage, RS-
232 physical layer transceiver (PHY) connected to a 2x5, 0.1”, pin header. The PHY supports
valid RS-232 signaling for input voltage levels down to +1.8V. The COM_SEL header selects
the serial path applied.
NOTE:
The COM_SEL header allows the SCI signals to be routed to the OSBDM.
However, the OSBDM does not support serial communications at this time.
RS-232
An RS-232 translator provides RS-232 to TTL/CMOS logic level translation on the COM
connector. The COM_PORT connector is a 2x5, 0.1”, pin header. Communication signals
TXD1 and RXD1 are routed from the transceiver to the MCU. Hardware flow control signals
RTS and CTS are available on the logic side of the transceiver. These signals are routed to
vias located near the transceiver. RTS has been biased properly to support 2-wire RS-232
communications. Figure 4 below shows the COM signal connections.

ACCELEROMETER
The TWR-S08 applies the MMA7361L, 3-axis, analog accelerometer for tilt and motion-sense
applications. The accelerometer supports 2 user selectable sensitivities - 1.5g / 6g. The
SLEEP* input allows the device to be placed in a low-power mode. Separate X-, Y-, and Z-
axis readings are routed to the MCU. Output filtering is applied to remove fast transients.
Configuration
Accelerometer sensitivity configuration is controlled manually using option select header JP2.
The SLEEP* input is configurable manually or under MCU control. Figure 7 below shows the
setting to configure the accelerometer output.

Buzzer
The TWR-S08 board provides an externally modulated piezo-buzzer for audible applications.
A push-pull drive circuit allows the target MCU to easily drive the buzzer at a center frequency
of 2400 Hz. Figure 9: below shows the option header settings for use with the buzzer.
Light Sensor
A surface-mount phototransistor, at RZ1, provides light sensitive, variable input for user
applications. Current flow within the phototransistor is inversely proportional to light intensity
incident on the surface of the device. A rail-to-rail OP amp at U5 boosts the photocell output to
useable levels. Figure 9: below shows the option header settings for use with the light sensor

Pushbutton Switches
The TWR-S08 applies 4, normally open, push-button switches for user input. Each push-
button switch is configured for active-low operation. A 22pF capacitor is applied to each push-
button switch to minimize switch bounce. An external pull-up is applied to SW4 for use as and
IRQ* input; however, no bias is applied to the remaining push-button inputs. Use of target
MCU internal pull-ups is required for proper operation.
Figure 10 below shows the user switch connections to the target MCU. Since each push-
button switch is normally-open, no option header is applied.
