<ol class="arabic simple">
<li><p>Running : Running 为代码正常运行时的功耗，由客户应用代码决定功耗。</p></li>
<li><p>WFI ：WFI 模式，只关闭了 CPU 以节省功耗，当用户退出 WFI 模式的时候程序将会继续运行。</p></li>
<li><p>PDS : PDS 模式，关闭了芯片上大多数电源域，同时关闭了 CPU ，可以通过内部 RTC 进行唤醒，或者使用特定的唤醒引脚唤醒。</p></li>
<li><p>HBN : HBN 模式，关闭了芯片上绝大多数电源域，关闭了 CPU ，可以通过内部 RTC 进行唤醒，或者使用特定的唤醒引脚唤醒。</p></li>
<li><p>Running : Running 为 CPU 正常运行时的功耗，由客户应用代码执行的功能决定功耗。</p></li>
<li><p>WFI ：WFI 模式，CPU 的 clock 处于被 Gating 状态，CPU 停止运行，当用户退出WFI模式的时候程序将会继续运行。</p></li>
<li><p>PDS : PDS 模式，关闭了芯片上大多数电源域，同时关闭了 CPU，和 CPU 处于同一个电源域的 ITCM，DTCM 等 RAM 不可使用，只有 64K 的 OCTAM 可以保存数据，可以通过内部 RTC 进行唤醒，或者使用 GPIO 引脚(在 GPIO 电源域没有关闭的情况下)唤醒。</p></li>
<li><p>HBN : HBN 模式，关闭了芯片上绝大多数电源域，关闭了 CPU 以及 64K OCRAM，只有位于 AON 域的 4K RAM 可以保存数据，可以通过内部 RTC 进行唤醒，或者使用特定的唤醒引脚(位于 AON 域的引脚)唤醒。</p></li>
