cc26xx udma能实现ram到flash的传输吗？

datasheet中介绍如下，似乎可以是ram到peripherals，但flash不行，不知理解是否正确？

The μDMA controller can perform transfers between memory and peripherals. The controller has dedicated channels for each supported on-chip module, and can be programmed to automatically perform transfers between peripherals and memory as the peripheral is ready to transfer more data.

μDMA控制器可以进行内存和外设之间传输。控制器已经专门为每个支持的片上模块通道，并且可以被编程为外设准备好传送更多的数据，以自动执行外围设备和存储器之间传输。

据我所知Flash应该是在外设的总线上挂着，所以，应该可以

从介绍中看，好像没有flash的channel
