If :ref:`CONFIG_PM_POWER_DOWN_PERIPHERAL_IN_LIGHT_SLEEP` is enabled, when the driver initializes the peripheral, the driver will register the working register context of the peripheral to the sleep retention link. Before entering sleep, the ``REG_DMA`` peripheral reads the configuration in the sleep retention link, and back up the register context to memory according to the configuration. ``REG_DMA`` also restores context from memory to peripheral registers on wakeup.
Currently ESP-IDF supports Light-sleep context retention for the following peripherals:

For peripherals that do not support Light-sleep context retention, if the Power management is enabled, the ``ESP_PM_NO_LIGHT_SLEEP`` lock should be held when the peripheral is working to avoid losing the working context of the peripheral when entering sleep.
