ERR
STATUS
○
○
[Script error]
(1)Is Hxw File Type correctly
selected when you convert from HEX to Hxw?
RX family, please select Normal.
(2)Are the start address and the end
address of PBT and Hxw matched?
Please set “Hxw data domain setting” to “Manual”, and conform Hxw address with script
or conform script address with Hxw file.
○
◎
[Device error]
(1)Is MCU power voltage used in the normal range?
(2)Is wire connection of MCU and EFP-LC OK?
(3)Connector and/or IC socket may have a bad connection.
Please clean the connector and/or IC socket.
(4) it may not be matched with communication baud rate.
Please change the setting of baud rate.
○
●
[Command execution error]
(1) Is wire connection of MCU and EFP-LC OK?
(2) Connector and/or IC socket may have a bad connection.
Please clean the connector and/or IC socket.
(3) Is the data erased before blank command is executed?
In case it is erased with lock bit valid, please try erasing it with lock bit invalid.
(4) In case of QzROM, is it after read protect command is executed?
There is no way to cancel read protect. Please change MCU.

Supplementary information about the script error
The EFP-LC compare the addresses of Hxw file address and PBT file written in PBT file.
Script error will be raised if the following conditions are satisfied.
1. Start Address of the Hxw file
<=
Start Address of the Pbt file
2. End Address of the Pbt file
<=
End Address of the Hxw file
If an error occurs, such as program error or device error, recommend that you check the following steps.
1. MCU power supply voltage is within the normal range?
2. There are no problems in the wiring of the EFP -LC and MCU?
3. Poor contact has not occurred in the IC socket and connector?
With respect to poor contact, refer to “
10.2
About the poor contact
