Now data placed to Hex Editor Buffer from the beginning of 0x0400 address.
If more complicated operations with files required, for example load Hex Editor Buffer from
many files “Lowest Address From File To Load”, “Highest Address From File To Load” and
“Clear Buffer Before Loading File” options are available.
6.2 SAVE FILE FROM BUFFER
Select “File>Save” menu item.
Press “Browse” button.
Select directory in which file will be saved.
Type file name, for example “test1”
Press “Save” button.
Than select format in which file will be saved*.
Press “OK” button.
&Note: Use EEF Format for future “Load File Into Buffer” automatically

7. ERRORS AND TROUBLESHOOTING
This section describes most recently encountered problems, errors and fixing solutions.
Problem: LED D1 (see Figure 1) Dark.
Causes: This problem can accrue when external power supply connected to HC912-
Programmer is damaged or connected in wrong polarity.
Solutions: Check voltage on HC912-Programmer power clamps. It must be 12 V +/- 1V.
Problem: LED D1 (see Figure 1) Red.
Causes: These problem can appear in two cases: if HC912-Programmer is in the service
mode (JP1 removed) and if some error accrue while operation of HC912-
Programmer.
Solutions: Insert jumper JP1 (see Figure 1), remove adaptors from Motorola device socket
and cable from ICP connector, turn-off and than turn-on power supply connected
to HC912-Programmer. If LED D1 still red contact ETL technical support.
Error Message: MC68HC912 Programmer not found
Causes: This message can appear when HC912-Programmer software couldn’t

Causes: This message can appear in In-Circuit programming interface when MCU
EEPROM/FLASH erased (all data equal to $FF) and accordingly device
still secured.
Solutions: Check voltage on VCC pins. Try to reconnect to target MCU.
Error Message: Voltage on VFP pin is below normal programming voltage level
Causes: This message can appear when no or low voltage applied to VFP pin.
Solutions: Apply specified by Motorola voltage to VFP pin.
Error Message: On-Board Programming Interface not supported for the Device
Causes: This message can appear when wrong Device selected.
Solutions: Select correct device type; take attention on MCU maskset.
Error Message: External power supply must be disconnected from BDM ICP connector
Causes: This message can appear in On-Board programming interface when
external voltage applied to BDM ICP connector (see Figure 1).
Solutions: Disconnect cable from BDM ICP connector.
Error Message: Vreg Overcurrent Protection
Causes: This message can appear when current consumption from built-in power
supply grater than 500 mA.
Solutions: Check target MCU power pins on short circuit.
Error Message: Vreg Output Voltage out of range
CYPRESS IIC BUS Busy
CYPRESS IIC Protocol Failed
