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

through a common interface, PGM_MTP. The programming functions are selected by

setting up the microcontroller’s registers before making a call to PGM_MTP at FFF0h.

Results are returned in the registers.

When several Bytes have to be programmed, it is highly recommended to use the Atmel

API “PROGRAM DATA PAGE” call. Indeed, this API call writes up to 128 Bytes in a sin-

gle command.

All routines for software access are provided in the C Flash driver available at Atmel’s

web site.
