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. Results are returned in the registers.
The IAP calls are shown in Table 2.
Table 2. IAP calls
IAP CALL
PARAMETER
PROGRAM DATA BYTE
Input Parameters:
R0H = 02h or 92h
R6 = address of byte to program
R4L = byte to program
Return Parameter
R4L = 00 if pass, non-zero if fail
ERASE BLOCK
Input Parameters:
R0H = 01h or 93h
R6H = block number in bits 7:5, bits 4:0 = ’0’

R6H = 00h
R6L = 00h – security bit # 1 (inhibit writing to FLASH)
01h – security bit # 2 (inhibit FLASH verify)
02h – security bit # 3 (disable external memory)
Return Parameter
none
PROGRAM STATUS BYTE
Input Parameters:
R0H = 06h
R6H = 00h
