For more information on how to configure the hardware flow control options, please refer to :example:`peripherals/uart/uart_echo`.
.. only:: SOC_UART_SUPPORT_SLEEP_RETENTION
Additionally, :cpp:member:`uart_config_t::backup_before_sleep` can be set to enable the backup of the UART configuration registers before entering sleep and restore these registers after exiting sleep. This allows the UART to continue working properly after waking up even when the UART module power domain is entirely off during sleep. This option implies an balance between power consumption and memory usage. If the power consumption is not a concern, you can disable this option to save memory.

.. only:: SOC_UART_SUPPORT_SLEEP_RETENTION
此外,置位 :cpp:member:`uart_config_t::backup_before_sleep` 会使能在进入睡眠模式前备份 UART 配置寄存器并在退出睡眠后恢复这些寄存器。这个功能使 UART 能够在系统唤醒后继续正常工作,即使其电源域在睡眠过程中被完全关闭。此选项需要用户在功耗和内存使用之间取得平衡。如果功耗不是一个问题,可以禁用这个选项来节省内存。
