 - SW2：切换启动时的 OTA 开关
   - ON：连接 WiFi 获取更新，如未能连接到 WiFi 则会持续到连接成功后才能启动
   - OFF：跳过检查更新，直接启动
-- SW3：切换 LED 亮度
-  - ON：全亮度
-  - OFF：亮度降低到指定值
+- SW3：无卡测试模式，适用于在没有卡片的情况下模拟读取代码指定的卡，例如授权卡
+  - ON：跳过读卡，使用硬编码的 `mifare_data` 数据
+  - OFF：读取实际卡片
 - SW4：不同模式的功能切换
   - Spice 模式（可在运行中切换）
     - ON：卡号发送到 2P 槽位（需要游戏支持）
