10.3 Modifying Flash Program Memory

When modifying existing data in a program memory

row, and data within that row must be preserved, it

must first be read and saved in a RAM image. Program

memory is modified using the following steps:

1. Load the starting address of the row to be

modified.

2. Read the existing data from the row into a RAM

image.

3. Modify the RAM image to contain the new data

to be written into program memory.

4. Load the starting address of the row to be

rewritten.

5. Erase the program memory row.

6. Load the write latches with data from the RAM

image.

7. Initiate a programming operation.
