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.
