On {IDF_TARGET_NAME}, the config option :ref:`CONFIG_SPI_FLASH_AUTO_SUSPEND` allows the cache to read flash concurrently with SPI1 operations. This is an optional feature that depends on special SPI Flash models, hence disabled by default. See :ref:`auto-suspend` for more details.
|

|
||||
If this option is disabled, the caches must be disabled while reading/writing/erasing operations. There are some constraints using driver on the SPI1 bus, see :ref:`impact_disabled_cache`. This constraints will cause more IRAM/DRAM usages.

在 {IDF_TARGET_NAME} 上,配置选项 :ref:`CONFIG_SPI_FLASH_AUTO_SUSPEND` 允许 Flash 的 cache 访问和 SPI1 的操作存并发地执行。该选项是可选的,依赖于特定的 SPI Flash 型号,因此默认是关闭的。请参阅 :ref:`auto-suspend`,查看详细信息。
|

|

然而当该选项被禁用时,读取/写入/擦除 flash 时, cache 必须被禁用。使用驱动访问 SPI1 的相关约束参见 :ref:`impact_disabled_cache` 。这些约束会带来更多的 IRAM / DRAM 消耗。
