＊１･･･ Maximum frequency of
“00” output is 512
times and continue transmitting until a reply from the target（
15
RXD）
Even “00” output is done 512 times when there is no reply, an error occurs.
＊2･･･ Only R8C Tiny series MCU is 100msec.

Don’t select the same MOT/HEX file in the normal area file and secondary area file.
If the same name is used, even another file, HDU file is overwritten when the original file, HDU format is converted
(If this mistake is made, our FM-ONE Project File Maker issues a warning message).
As many as 10 file folders in the CF can be perceived by FM-ONE.
If more than 10 file folders are in the CF root, FM-ONE will detected 10 files voluntarily and display them on LCD
screen. The order of display cannot be designated.
Files other than the project can be placed in the CF, it is recommended that such files be packed into a single
folder to avoid trouble of confirming unnecessary files as circumstances permit.
When files other than the project are placed in the CF, we don’t recommend that too many files be not placed as
file checking is troublesome.(Unless the folder is selected as a project, file checking is not done inside. If that
folder is selected by mistake, we will not guarantee.
Project is displayed under the folder name. Make sure that files with different
names are not put in the
folder as it cannot be confirmed.
While the access lamp is on, never take out the CF as saved data may be destroyed.
If CANCEL button is pushed three times consecutively of the Project selection screen,
functions other than
Write and Cancel are locked.
Don’t use the converted user File HDU on another MCU because ROM areas cannot be confirmed.
