 ### 14) AW8737A 脉冲控制
 
-- `setAw8737aPulse`/`refreshAw8737aPulse`
+- **脉冲模式**
+  - `setAw8737aPulse(pin, pulseNum, refresh)`: 设置脉冲数量（0-3）
+  - `refreshAw8737aPulse`: 触发脉冲刷新
+- **增益模式**（语义化别名）
+  - `setAw8737aMode(pin, mode, refresh)`: 设置增益模式（MODE_1 到 MODE_4）
+  - `refreshAw8737aMode`: 触发模式刷新
+- **注意事项**
+  - 如果引脚不是输出模式，会自动配置为推挽输出
+  - 如果使用开漏输出，需要外部上拉电阻
+  - refresh=NOW 时执行后会有 20ms 延迟

 ### 14) AW8737A Pulse Control
 
-- `setAw8737aPulse`/`refreshAw8737aPulse`
+- **Pulse Mode**
+  - `setAw8737aPulse(pin, pulseNum, refresh)`: Set pulse count (0-3)
+  - `refreshAw8737aPulse`: Trigger pulse refresh
+- **Gain Mode** (semantic aliases)
+  - `setAw8737aMode(pin, mode, refresh)`: Set gain mode (MODE_1 to MODE_4)
+  - `refreshAw8737aMode`: Trigger mode refresh
+- **Notes**
+  - If pin is not output mode, it will be auto-configured as push-pull output
+  - If using open-drain output, external pull-up is required
+  - When refresh=NOW, there will be a 20ms delay after execution
