 When power management is enabled via :ref:`CONFIG_PM_ENABLE`, the system may adjust or disable clock sources before entering sleep mode, which could cause TWAI to malfunction. To prevent this, the driver manages a power management lock internally. This lock is acquired when calling :cpp:func:`twai_node_enable`, ensuring the system does not enter sleep mode and TWAI remains functional. To allow the system to enter a low-power state, call :cpp:func:`twai_node_disable` to release the lock. During sleep, the TWAI controller will also stop functioning.

+    About Sleep Retention
+    ^^^^^^^^^^^^^^^^^^^^^
+
+    {IDF_TARGET_NAME} supports powering down the TWAI controller during **Light Sleep** to further reduce power consumption and automatically restore after waking up. This means the application does not need to reconfigure TWAI after **Light Sleep** wake up.
+
+    Enable the option :ref:`CONFIG_PM_POWER_DOWN_PERIPHERAL_IN_LIGHT_SLEEP`, and set :cpp:member:`twai_onchip_node_config_t::flags::sleep_allow_pd` to ``true`` when initializing the TWAI node to enable this feature. Otherwise, the TWAI controller will remain powered during **Light Sleep**. This feature helps reduce power consumption during light sleep but requires additional storage to save register configurations.

 当启用电源管理 :ref:`CONFIG_PM_ENABLE` 时，系统在进入睡眠模式前可能会调整或关闭时钟源，从而导致 TWAI 出错。为了防止这种情况发生，驱动内部使用电源锁管理。当调用 :cpp:func:`twai_node_enable` 函数后，该锁将被激活，确保系统不会进入睡眠模式，从而保持 TWAI 功能正常。如果需要降低功耗，可以调用 :cpp:func:`twai_node_disable` 函数来释放电源管理锁，使系统能够进入睡眠模式，睡眠期间 TWAI 控制器也将停止工作。

+    {IDF_TARGET_NAME} 支持在 **Light Sleep** 期间将 TWAI 控制器断电以进一步降低功耗，并在唤醒后自动恢复。即程序不需要在 **Light Sleep** 唤醒后重新配置 TWAI。
+
+    启用选项 :ref:`CONFIG_PM_POWER_DOWN_PERIPHERAL_IN_LIGHT_SLEEP`，并在初始化 TWAI 节点时，将 :cpp:member:`twai_onchip_node_config_t::flags::sleep_allow_pd` 设置为 ``true`` 即可启用该功能，否则 TWAI 控制器在 **Light Sleep** 期间将保持供电。它可以帮助降低轻度睡眠时的功耗，但需要花费一些额外的存储来保存寄存器的配置。
