11.3.2.4.1 Page Write Command
The Page Write (FLPW/EEPW) commands write the content of the page buffer to the Flash or EEPROM.
If the write is to the Flash, the CPU will execute code as explained in 11.3.1.1.1 Physical Sections.
If the write is to the EEPROM, the CPU will continue executing code while the operation is ongoing. Erase the page/byte before performing a write.
The page buffer used will automatically be cleared after finishing the operation.
