In-Application Programming Method
Several Application Program Interface (API) calls are available for
use by an application program to permit selective erasing and
programming of FLASH sectors. 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.
The API calls are shown in Table 3.
