Part Number: TPS65987D
Other Parts Discussed in Thread: TPS65987, , SN74LVC1G07

TPS65987 GUIアプリケーションソフトウェアを使用してbinファイルを生成することができました。
この内容について質問があります。
GPIOの設定が「無効」の場合、端末は高インピーダンス状態になりますか?
(2).GPIOを制御せずに任意の固定値(HまたはL)に設定することは可能ですか?
(3).GPIO設定 「マップされたイベント」には複数の項目があります。選択方法のマニュアルはどこで入手できますか?

    Hi Yamamotoju,

    In the future, please translate your questions to English. I used Google Translate to translate your original questions, but I do not know if the translation was done correctly.

    I was able to generate a bin file using the TPS65987 GUI.

    I have a question regarding this content.

    If GPIO is disabled, will it go into a high impedance state?

    [TI] Yes

    2. Is it possible to set any fixed value without controlling the GPIO

    [TI] I am not sure what you are asking here, there is an event called "Output Enabled without Event" that you may want to look into

    3. There are many GPIO mapped events in the GUI, where do I get a selection manual.

    [TI] Please refer to the technical reference manual that is found on the TPS65987D product page. There is a section on GPIO Events (3.36.2).

    Thanks and Regards,

    Chris

    Dear Chris
    We apologize for the inconvenience and will reply in English.
    Thank you again for your reply.

    ``2''.I have an inquiry, but please let me confirm again.
    In our system, GPIO20 (54Pin) of "TPS65987D" was originally assigned as "USB3_VBUS_detection", but it is no longer used, but since it is connected to the input side of SN74LVC1G07, we want to output "L" level (0V) instead of high impedance. However, I would like to know the settings for "Mapped Event" in that case.

    No worries, I just want to make sure information is not lost in translation.

    You should be able to use the "Output Enabled Without Event" GPIO Mapped event to do this. Configure the initial value as 0x00 to assert low.
