7.3.2.2.1 Flash Page Erase

A page erase is necessary before programming the Flash memory. This will ensure that the old contents of the page are erased and programmed with all 1’s before programming with new content. Prior to a page erase operation, the target page is selected by writing an address within the page into the Write Address register, NVMADR. A page erase will erase eight rows of data concurrently.
