11.3.2.4.4 Page Erase/Write Operation
Page Erase and Write (FLPERW/EEPERW) commands are a combination of Page Erase and Page Write commands, but without clearing the page buffer after the Page Erase command. The erase/write operation first erases the selected page, then writes the content of the page buffer to the same page.
When performed on the Flash, the CPU will stop or continue based on the same conditions as for the Page Write command. When performed on the EEPROM, the CPU will continue executing the code.
The page buffer used will automatically be cleared after finishing the operation.
