# rccgpio.4

`rccgpio` — ADI Engineering RCC-VE 与 RCC-DFF/DFFv2 GPIO 控制器

## 名称

`rccgpio`

## 概要

`device rccgpio device gpio device gpioled`

## 描述

`rccgpio` 提供了一个简单接口，用于读取复位开关状态并控制状态 LED。

已知的由软件控制的复位开关仅出现在 Netgate 的主板上。大多数用户得到的是一个硬件复位按钮。

所有 GPIO 引脚都被锁定在其预期设置中，以禁止任何可能有害的设置（即可能导致短路的设置）。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/rccgpio.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
