 The driver can prevent the above issue by creating a power management lock. The lock type is set based on different clock sources. The driver will acquire the lock in :cpp:func:`rmt_enable`, and release it in :cpp:func:`rmt_disable`. That means, any RMT transactions in between these two functions are guaranteed to work correctly, regardless of the power management strategy. The clock source won't be disabled or adjusted its frequency during this time.

     Besides the potential changes to the clock source, when the power management is enabled, the system can also power down a domain where RMT register located. To ensure the RMT driver can continue work after sleep, we can either backup the RMT registers to the RAM, or just refuse to power down. You can choose what to do in :cpp:member:`rmt_tx_channel_config_t::backup_before_sleep` and :cpp:member:`rmt_rx_channel_config_t::backup_before_sleep`. It's a balance between power saving and memory consumption. Set it based on your application requirements.

     除了时钟源的潜在变化外，当启用电源管理时，系统还可以关闭 RMT 寄存器所在的电源域。为确保 RMT 驱动程序在睡眠后继续工作，用户要么选择将 RMT 相关的寄存器备份到 RAM 中，要么拒绝关闭电源域。你可以根据应用需求在 :cpp:member:`rmt_tx_channel_config_t::backup_before_sleep` 和 :cpp:member:`rmt_rx_channel_config_t::backup_before_sleep` 中设置是否需要启用寄存器备份，在功耗和内存使用之间做权衡。
