### 代表的な半導体機能の割り当て

各ピンは標準的な入出力に対応するDIO(GPIO)として機能するほか、UART,SPI,I2Cといった機能を有効にすることが出来ます。代表的な割り当て、またAPIの指定する手続きにより切り替えられる代替割り当てについて紹介します。詳しくは半導体データシートを参照ください。

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://twelite.gitbook.io/general/technical-info/pin-assign.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
