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
HCS12(X) instruction set and a host PC running a debug interface. CodeWarrior Development
Studio is supplied with this board for application development and debug.
Refer to the
supporting CodeWarrior documentation for details on use and capabilities.
NOTE:
OSBDM is not functional at this time and will provide power to the
board only. Updated OSBDM firmware is expected in August 2010 to
support the HCS12 target. An external BDM is required to program
and debug the target MCU.
DEVELOPMENT SUPPORT
Application development and debug for the target TWR-S12 board is supported through the
Open-Source Background Debug Mode (OSBDM) interface or an external BDM interface
connector. 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-S12
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:
OSBDM is not functional at this time and will provide power to the
board only. Updated OSBDM firmware is expected in August 2010 to
support the HCS12 target. An external BDM is required to program
and debug the target MCU.

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
allows the user to update OSBDM firmware easily and quickly. Option jumper JP401 enables
the bootloader at startup. This option header 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 J3.
This header allows the use of external programming/debug cables. Refer to the external
programming/debug cable documentation for details on use. The figure below shows the pinout for the DEBUG header.
NOTE:
OSBDM is not functional at this time and will provide power to the board
only. Updated OSBDM firmware is expected in August 2010 to support the
HCS12 target. An external BDM is required to program and debug the
target MCU.

POWER
The TWR-S12 board may be powered from the OSBDM, from the Tower System, from the LIN
+V input, or 2 input vias at E1 & E2. The LIN +V input accepts +12V from the LIN bus and
uses an on-board regulator to create the board operating voltage. Input vias at E1 & E2 allow

connecting external power to the board if desired. An on-board regulator is used to create the
board operating voltage from this input.
Use of the on-board regulator requires input voltage between +7.V and +27V. However, input
voltage should be kept as low as possible to reduce device self-heating.
CAUTION:
This boards does not apply reverse polarity protection on inputs E1 &
E2. Polarity for each input is clearly marked. Reverse input polarity
will damage the board.

RESET SWITCH
The RESET switch applies an asynchronous RESET input 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.
LOW VOLTAGE RESET
The MC9S12G128 applies a Power-On Reset (POR) circuit and an internal Low Voltage
Reset (LVR) circuit to ensure proper device operation. The POR circuit holds the MCU in
reset until applied voltage reaches an appropriate level. The LVR forces the device into reset
if input voltage falls too low, protecting against brown-out conditions. A user configurable LowVoltage Detect (LVD) with interrupt output is also available. Consult the MC9S12G128
reference manual for details of POR, LVR, and LVD operation.

TIMING
The TWR-S12G128 internal timing source is active from RESET by default. An external 8MHz
crystal oscillator, configured for low-power operation, is also installed. Refer to the target
device RM for details on selecting and configuring the desired timing source.
COMMUNICATIONS
Communications options for the TWR-S12G128 include serial RS-232, LIN, and CAN. Serial
RS-232 communications is supported through a RS-232 physical layer device (PHY) and a 2x5
pin header. A high-speed, enhanced, LIN PHY provides LIN bus communications through a
2x2 Molex connector (pn 39-29-1048). A high-speed CAN PHY provides CAN bus
communications through a 1 x 4 Molex connector (pn 39-30-3045).
Connecting LIN cables require Molex housing, pn 39-01-2040 and pins, pn 39-00-0217.
Connecting CAN cables require Molex housing, pn 39-01-4040, and pins, pn 39-00-0217.
The COM_SEL option header connects the MCU SCI signal to either the LIN PHY or the RS232 PHY. See Figure 6 below for jumper position options. See Figure 4 below for jumper
position options.
RS-232
The TWR-S12G128 applies the MAX3387E, RS-232 transceiver to support serial
communications. A standard 2x5 “Berg” pin-header on 0.1” centers and an IDC to DB9 cable
supports connecting standard serial cables to the target board. Figure 4 below shows the SCI
signal connections.

The LIN interface provides optional features of slew rate control, network supply, and wake up
option. Refer to the MC33661 Reference Manual for detail on PHY functionality. The following
sections detail functionality for LIN option jumpers.
LIN Enable
The LIN PHY is enabled by default. Disable the PHY by connecting the test point, TP3, to
GND.
LIN COM Input
LIN inputs RX and TX are selectable using the COM_EN option header. Refer to Figure 6
above for details on configuring this header.
LIN_PWR Option
The LIN_PWR option jumper connects pin 1 of both LIN connectors to the +V input. In Master
mode, this option may be used to power LIN slave devices. This option requires +12V be
applied at E1/E2 inputs. In Slave mode, this option allows slave device to draw power from the
LIN network. For Slave mode configuration, external power should not be applied to the target
board. LIN_PWR is enabled by installing a shunt from JP3-1 to JP3-2. Refer to Figure 8
below.
CAUTION:
If the target board draws power from the LIN bus in Slave mode, do
not apply external power at E1/E2 inputs. Damage to the board may
result.
NOTE:
If the target board powers the LIN bus in Master mode, +12V must be
applied externally at E1/E2 inputs.
MSTR Option
The MSTR option jumper allows the LIN transceiver to be configured for Master mode
functionality. Master mode may also be set using the INH pin on the PHY. Refer to the
MC33661 device datasheet for details on use and configuration. Refer to Figure 8 below.
