In Application Programming Method
Several In Application Programming (IAP) 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. The oscillator frequency is an integer number rounded down
to the nearest megahertz. For example, set R0 to 11 for 11.0592 MHz.
Results are returned in the registers. The API calls are shown in
Table 9.
