80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI
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, 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.
Table 12.
IAP function calls
IAP function
IAP call parameters
Read Id
Input parameters:
R1 = 00H or 80H (WDT feed)
DPH = 00H
DPL = 00H = manufacturer id
DPL = 01H = device id 1
DPL = 02H = device id 2
DPL = 03H = 6x/12x bit (bit 7 = 1 = 6x)
DPL = 80H = ISP version number
Return parameter(s):
ACC = requested parameter
Erase 8 kB/16 kB code block
Input parameters:
R1 = 01H or 81H (WDT feed)
DPL=00H, block 0, 0kB to 8kB
DPL = 20H, block 1, 8 kB to 16 kB
DPL = 40H, block 2, 16 kB to 32 kB
DPL = 80H, block 3, 32 kB to 48 kB
DPL = C0H, block 4, 48 kB to 64 kB
Return parameter(s):
ACC = 00 = pass
ACC = !00 = fail
Program User Code
Input parameters:
R1 = 02H or 82H (WDT feed)
DPH = memory address MSB
DPL = memory address LSB
ACC = byte to program
Return parameter(s):
ACC = 00 = pass
ACC = !00 = fail
Read User Code
Input parameters:
R1 = 03H or 83H (WDT feed)
DPH = memory address MSB
DPL = memory address LSB
