Several In-Application Programming (IAP) calls are available for use by an application 
program to permit selective erasing and programming of Flash sectors, pages, security 
bits, configuration bytes, 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 FF03H. The IAP calls are shown in 

.

(This feature was not present in the original P89LPC932).
