User’s Manual — EVB912UF32
1.1 Description
This user’s manual explains how to connect and operate the Motorola
EVB912UF32 Evaluation Board (EVB).
This board is a development tool which allows the user to run software
applications for MC9S12UF32 microcontroller unit (MCU).
The EVB912UF32 includes connectors for CompactFlash, SmartMedia, Secure
Digital/Multimedia, and Memory Stick cards as well as a standard 40 pin ATA
interface. The system also features a USB 2.0 interface. The board has several
20-pin headers that are connected to most of the processors signals. These
provide convenient points to observe these signals or connection points for
external user designed circuit boards.
General Information

2.5 Using the Memo ry Cards
The users must obtain their own compatible cards for use with these connectors.
Please note the power for most of these cards is connected to P3.3V which is
+3.3 volts. The CompactFlash (CF) connectors are power by VDDX that can
switch between zero volts, +3.3 volts and +5 volts under software control. W19
selects power to the control signals of all memory card connectors except J11
(the top side CF). VDDX always powers the control signals to J11. The user

Configuration and Operation
Using the Memory Cards
must exercise caution not to select VDDX when using the SD/MMC, Memory
Stick, or SmartMedia cards. Use W19 to select VDDX as the power source for
VDD3X when using the bottom side CompactFlash, J13. Some of the signals
on J13 are directly powered by VDDX and the rest are referenced to VDD3X.
Caution: W19 must not select VDDX for VDD3X power when using the
SD/MMC, Memory Stick, or SmartMedia cards.
Caution: To avoid circuit damage, do not plug in SmartMedia, SD/MMC, or
Memory Stick cards with power applied to the board.

3.1 Introduction
This section consists of connector pin assignments, connector signal
descriptions, and other information that may be useful in your development
activities. For the ATA and memory card interfaces, signals described as
outputs are signals that originate from the external device. Input signals
originate on the board going to the device.
3.2 Top CompactFlash Connector
Connector J11 is one of two CompactFlash connectors on the EVB912UF32.
This connector shares signals with the ATA connector, J2, so these connectors
cannot be used at the same time. To use a CompactFlash card and the ATA
interface simultaneously, use the bottom CompactFlash connector, J13. Note
that when using J13, W19 should select VDDX as the VDD3X power source.
Section 3 Support Information
Figure 3-1 gives pin assignments for the top CF connector, J11. Figure 3-2
gives pin assignments for the bottom CF connector. The signal names match the
names used in the schematic and may not be the signal name normally
associated with CompactFlash. Table 3-1 gives signal descriptions for these
connectors. The signal names on the table might not match the schematic or the
figures. Instead they show the intended CompactFlash function that must be
selected for that particular pin.

4.1 Description
This section discusses common operational issues and how to resolve them.
4.2 Common Issues
4.2.1 System +5V PWR LED is not lit
Troubleshooting
Description
Section 4 Troubleshooting
Check the EVB912UF32 for power:
1. Verify the power supply is plugged in and the wall outlet has power.
2. Verify that S1 is in the ON position and the power jack is plugged
securely into J20.
3. Check that voltage is available at J22, the +12V test loop.
4. Check that the fuse, F1, is not open. If it is, replace the fuse.
4.2.2 BDM communications are not working.
Communication with the board through the BDM interface, J3, stops working
or will not work.
1. Verify power is properly applied to the boar d. (See 4.2.1.)
2. Verify a valid clock source is selected at W1. Normally the on board
12MHz crystal will be used which requires W1 pins 1-2 to be jumpered.
3. Verify the external Multi-link device is connected to J3 and powered.
4. Verify there is an active USB connection from the Multi-link to the PC.

5. Verify the MOD jumpers (W13, W16, and W18) are configured for
Normal Single Chip operation.
4.2.3 The ATA is non-functional
Cannot get the ATA interface working or it quits working.
1. Ensure the ATA parallel cable is connected to J2 and to the ATA device.
2. Verify there is no CompactFlash ( CF) card installed at J 11. J13 can have
a CF card installed.
3. Verify that Voltage Generation is enable with a jumper across W11 pins
1-2.
4. Verify the program is enabling VDDX power. Either DS1 or DS2 is lit.
5. Check that a jumper is installed at J8 (VDDX) and the selected voltage
is available there.
6. Verify power as per Sec. 4.2.1.
4.2.4 Top CompactFlash J11 is non-functional
Cannot get the J11 CF interface working or it quits working.
1. Verify the CompactFlash card is installed correctly. Both rows of pins
are making contact.
2. Verify there is no CompactFlash (CF) card installed at J13.
3. Verify the ATA interface is not connected.
4. Verify power as per Sec.4.2.1.
4.2.5 Bottom CompactFlash J13 is non-functional
Cannot get the J13 CF interface working or it quits working.
1. Verify the CompactFlash card is installed correctly. Both rows of pins
are making contact.
2. Verify there is no CompactFlash (CF) card installed at J11.

3. Verify no SD/MMC, Memory Stick, or SmartMedia card is installed.
4. Verify that W19 1-2 is jumpered to select VDDX for VDD3X.
5. Verify power as per Sec. 4.2.1.
4.2.6 The SD/MMC, Memory Stick, or SmartMedia is non-functional
One or more of these memory cards can not be made to function or quits
functioning.
1. Verify the problem memory card is installed correctly.
2. Make sure no CompactFlash card is installed in J13.
3. Verify that Voltage Generation is enable with a jumper across W11 pins
1-2.
4. Verify that W19 1-2 is jumpered to select P3_3V for VDD3X
Troubleshooting
Common Issues
5. Verify that the voltage at the J18 test loop measures +3.3V.
6. Verify power as per Sec. 4.2.1.
4.2.7 The USB 2.0 Interface is non-functional
USB 2.0 communications stop working or can not be enabled.
1. Verify the USB cable is installed correctly.
2. Verify the host PC system sees the board as a USB device.
3. Verify power as per Sec. 4.2.1.
4.2.8 The RS-232 Communication is non-function
The RS-232 interface is not working or quits working.
1. Verify J31 is connected to a host with an RS-232 port.
2. Verify that W6 and W5 have a jumper installed.
3. Verify power as per Sec. 4.2.1.
4. Try looping back RS-232 control signals using W14, W15, and W17.
