Product data sheet
6.3.8 IAP method
Several IAP calls are available for use by an application program to permit selective
erasing, reading and programming of flash pages, security bits, status bit, and device ID.
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 IAP calls are shown in
Table 12.
