Like Igor and Jonatan said, reading from the Flash is as simple as reading
from a memory location. However, writing to flash is a bit complicated. If
you are looking for a simple command to write to a particular location, you
should know that that is not possible.
Read the above mentioned Application Note and also refer to this old thread
and that might give you some ideas.

Hello ronak,

You don't need IAP to read flash. All flash is mapped to memory, so
just read data from the specific address you want.

Hi,
Thanks for the solution. But is it
possible to read from the flash memory during run time using IAP commands? If so
then please provide the IAP commands for the same since these kind of commands
are not given in manual.

Read about IAP in the UM.

Hi All,
I am using lpc2103 for my application. The application is such that some
of the parameters are required to be stored into and retrieved from the flash
memory during run time. So, is it possible to read from and write into the
lpc2103 flash memory during run time?
Kindly provide the available solution for this issue.
