Does nRF52840 support Flash Erase suspend (and resume) operation (internal flash)?

[Harry]

I was wondering, is it possible to suspend/resume flash operation in nRF52840 (internal flash)? Like flash erase suspend, and also flash write suspend/resume?

Thank you.

Hi,

On 52840, it is possible to split a page erase into multiple operations, see Partial erase of a page in flash. But note that this feature is not supported by the Softdevice's flash API so it needs to be performed while the softdevice is disabled. 

We do not have support for partial write operations, but those are much faster to perform.

Thanks Vidar! Awesome!
