看门狗可以从深度睡眠中唤醒BlueNRG-2吗？

嗨彼得，
看门狗外设在休眠或待机模式下不工作，因为在这些模式下不提供数字电源（保持RAM保持所需的电源除外）。
请使用SLEEP_MODE_CPU_HALT模式，使用此省电模式，电流消耗约为1.5 mA。
请参考项目：

谢谢。
最好的祝福，
温弗雷德

Hi Piotr,
The watchdog peripheral does not work in Sleep or Standby mode, because in these modes the digital power is not supplied (except the power necessary to keep the RAM in retention).
Please use SLEEP_MODE_CPU_HALT mode instead, using this power saving mode the current consumption is around 1.5 mA.
Please reference the project:

Thank you.
Best Regards,
Winfred

你好Winfred，
我在芯片文档中找到了有关此主题的更多信息：
1）SLEEP和STANDBY状态之间存在细微差别：在睡眠状态下，慢速时钟正在运行，但在待机状态下则不是
2）看门狗由这个慢速时钟提供时钟
3）看门狗RST线连接到一个门作为BLE RSTs线的等效输入，而BLE RST可以通过RESET引脚激活。
这些只是文档中的观察和结论，我没有在圈选中进行验证，但是：
a）如果RESET引脚可以唤醒芯片，它可以通过BLE RSTs线来实现
b）BLE RSTs线和WDG RST是门的对称输入，因此WDG RST也可以复位芯片
c）看门狗由处于休眠状态的慢速时钟提供时钟
 
是否意味着看门狗可以将芯片从SLEEP状态唤醒？
 
问候，
Piotr Romaniuk

Hi Winfred,
I found more information on this topic in the documentation of the chip:
1) There is a small difference between SLEEP and STANDBY state: in sleep state slow clock is running but in standby it is not
2) Watchdog is clocked by this slow clock
3) Watchdog RST line is connected to a gate as equivalent input to BLE RSTs line, while BLE RST can be activated by RESET pin.

These are only observations and conclusions from the documentation, and I did not verified it in circut, but:
a) if RESET pin can wake up the chip, it does it by BLE RSTs line
b) BLE RSTs line and WDG RST are symetric input of the gate, so WDG RST can reset the chip as well
c) Watchdog is clocked from slow clock that is running in SLEEP state

Does it mean that watchdog can wake up the chip from SLEEP state?

Piotr Romaniuk
