WIC
概述
WIC（wake-up interrupt controller，唤醒中断控制器）用于中断检测并将处理器从深度睡眠模式唤醒。
WQ WIC 模块提供接口控制唤醒当前 core 以及当前 core 唤醒其他 core 的 API，并可以让其保持通电状态的接口。
用法流程
初始化
wq_wic_init()唤醒一个 core
wq_wic_awake()唤醒 core，并让其保持唤醒
wq_wic_keep_poweron()释放一个 core 的唤醒状态
wq_wic_release()注册一个当前 core 中断唤醒后函数句柄
wq_wic_register_wakeup_handle()
API 介绍
This section introduces the WIC module's functions and how to use this driver.
Typedefs
-
