Application
in FM0
Several Application Program Interface (API) calls are available for use by an application
program to permit selective erasing and programming of Flash pages. All calls are made
by functions.
All these APIs are describe in an documentation: "In-System Programing: Flash Library
for AT89C51AC3" available on the Atmel web site.
