Erases a contiguous flash section
The Page Erase 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.
