The memory architecture used in the NuMicro® microcontroller (MCU) is Flash and its operating procedure can be divided into the following three parts:

Erase Page
Program Flash
Read Verify Flash

To update a few data, you need to first backup data on the entire Page to RAM or Flash on different Pages that has been pre-erased, modify the data you want to change, and then write the modified data back into the memory through the following procedure:

Erase Page
Program Flash; write the modified data into the Flash
Read Verify Flash; compare and verify the Flash value with the modified value
