IRQ pin 拉低可以作为唤醒源<br />

<p dir="auto">但是实际测试却不行，哪位大神帮忙解答下？<br />
我是用i2c调试工具，步骤是：</p>
<ol>
<li>
<p dir="auto">先将 REG 26H[4] 设置为1（从0x08 写为0x18）<br />
<img src="/assets/uploads/files/1700983680362-dd8934bc-812a-4e7f-a8bf-9034240b12c3-image.png" alt="dd8934bc-812a-4e7f-a8bf-9034240b12c3-image.png" class=" img-responsive img-markdown" width="482" height="329" /></p>
</li>
<li>
<p dir="auto">然后写 REG 26H[0] 为1，进入休眠模式<br />
<img src="/assets/uploads/files/1700983772847-d32867d5-3397-4efb-97f1-147400209cff-image.png" alt="d32867d5-3397-4efb-97f1-147400209cff-image.png" class=" img-responsive img-markdown" width="1256" height="107" /><br />

</li>
<li>
<p dir="auto">按下板子上 IRQ pin，（当然有16ms）然后检查REG 26H[0] 寄存器没有恢复到 0，依然为0x19 (0b0001 1001)<br />
<img src="/assets/uploads/files/1700983915852-5fda0d27-869a-44fd-8892-7124f00fefbb-image.png" alt="5fda0d27-869a-44fd-8892-7124f00fefbb-image.png" class=" img-responsive img-markdown" width="479" height="332" /></p>
</li>
</ol>
<p dir="auto">请问哪位大神知道这是为啥，这功能还得找AXP定制么，如果没有外部按键wakeup，这芯片咋做到休眠唤醒上电的？</p>

<blockquote>
<p dir="auto">wakeup</p>
</blockquote>
<p dir="auto">根据 AXP2101 文档，IRQ 引脚可以是输入或输出。 设置睡眠模式时，您可以 当 IRQ 电路设置为低电平一段时间时，对引脚进行编程以从睡眠模式唤醒。<br />
控制器可以将电平设置为低。 控制器的 NMI 输出电路包含一个集电极开路晶体管开关 为了这些目的。 该密钥通过寄存器以编程方式控制。</p>
