The S12VR64EVB3 features the S12VR64 (maskset 0N59H which is the most
recent version of this MCU), an automotive 16-bit MCU. This family integrates an
S12 microcontroller with a LIN physical interface, a 5 V regulator system to supply
the microcontroller and analog blocks to control other elements of the system
which operate at vehicle battery level. The S12VR family uses many of the same
features found on the S12G family, including error correction code (ECC) on flash
memory, EEPROM for diagnostic or data storage, a fast analog-to-digital converter
(ADC) and a frequency modulated internal phase locked loop (IPLL) that improves
the EMC performance. This guide will show how to quickly connect the board to
a host PC and execute a demonstration application preloaded into flash memory.
Default jumper positions are for applications loaded on the S12VR64EVB3 board
and are shown on the following page.

Install CodeWarrior
Development Studio
The S12VR64EVB3 board ships with
the latest version of CodeWarrior
Development Studio for Freescale
HCS12(X) microcontrollers. CodeWarrior
Development Studio is a complete
Integrated Development Environment
(IDE) that provides a highly visual and
automated framework to accelerate
the development of the most complex
embedded applications.
NOTE: CodeWarrior Development Studios and
the provided PE OSBDM drivers, must be properly
installed before attempting to connect the target board
to the host PC. Otherwise, the necessary USB drivers
will not be available and the host PC will not recognize
the board.
CodeWarrior Development Studio for HCS12(X) V5.1
IDEV5.9 is included on the DVD provided and can
be found on the main screen or on the additional
resources tab.
Install CodeWarrior
Service Pack for S12VR
Family Microcontrollers
Double-click on the link for the S12VR
service pack. This patch contains header
files for the S12VR family microcontrollers.
NOTE: CodeWarrior Service Pack for S12VR is
included on the DVD provided and can be found on
the main screen or on the additional resources tab.
Launch the Demo
Program
The DVD contains a CodeWarrior project
to exercise the BATS module, ADC,
high-side drivers, the relay using low-side
drivers, Port T and SCI module. Please
follow the instructions below to compile
and load this code.
NOTE: If you want to connect a load on the relay
outputs, you’ll need to use a power supply with a
higher current output connected to the power supply
banana connectors J6 and J7.

1. Open CodeWarrior Development Studio.
2. Unzip the content of the EVB Source Code file
(evb_demo_application_3_0.zip) located on
the additional resources tab of the DVD.
3. Drag the unzipped file “evb demo application.
mcp” into CodeWarrior’s Window (the
file is located below directory “evb demo
application”). This action should open
CodeWarriors’ project explorer.
4. Press “F7” key to build the project.
5. Verify the option jumpers are set in default
positions. Refer to Figure 2.
6. Connect the included A/B USB cable between
an open USB port on the host PC and the
USB connector on the target board.
7. Install PE V11.1.1 OSBDM drivers (included
in the DVD). This allows using the OSBDM as
a USB to serial bridge and connect the board
to any serial terminal. Note: Virtual serial port
cannot be used with this driver. However,
serial terminals can connect through a COM
serial port.
8. Connect the power adaptor to the barrel plug
to power the device.
9. While in CodeWarrior’s window press “F5”; this
action will attempt to establish a connection
between the evaluation board and the PC.
10. Follow the instructions presented to connect
to the embedded debugger and download the
code recently compiled.
11. While in the debugger screen “True-Time
Simulator & Real-Time Debugger”, press “F5”
to start the code recently downloaded.
12. The relay will click on base time defined by
the potentiometer R51.
13. Open a terminal program and configure
for 19200, 8, none, 1, none. Open a serial
connection to OSBDM/OSJTAG- CDC
Serial Port.
14. Rotate the potentiometer and notice that the
relay switching time will change according to
the potentiometer.
15. Notice that the LEDs D13, D14, D15 and D16
will flash according to the relay changes.
16. Notice that the terminal program is reporting
the status of the system.
17. Program is reporting the status of the
VSENSE pin with an 8-bit resolution,
the current relay timer configuration on
milliseconds and the battery voltage status.
18. Adjust the supply voltage to be below or over the
thresholds and check on the terminal program
and the battery voltage status during this
operation. (The example program is using the
VLBI2 and VHBI1 thresholds, these thresholds
are defined on the 9S12VR RM).
19. While in the Debugger window, you can halt the
controller by pressing “F6” and add break points
in the code by right clicking on it and selecting
the option “Set Break Point”.
20. Pres “F1” while in the Debugger window or in
CodeWarrior Development Studio to open the
included help.
