Erase Section

Erases a contiguous flash section.

The Erase Section command will first unlock all regions which are within the requested flash range to erase. If the requested flash area (start address; pages) constitutes the entire flash of the device, the Erase All command will be used. Otherwise a sequence of page erases will be performed.

Note: Erasing sections can also be done by writing to the flash controller directly.
