API Call Description Several Application Program Interface (API) calls are available for use by an application program to permit selective erasing and programming of Flash pages. 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. Table 96. API Call Summary 138 AT89C51ID2 When several bytes have to be programmed, it is highly recommended to use the Atmel API “PROGRAM DATA PAGE” call. Indeed, this API call writes up to 128 bytes in a single command. All routines for software access are provided in the C Flash driver available on Atmel web site. The API calls description and arguments are shown in Table Command R1 A DPTR0 DPTR1 Returned Value Command Effect READ MANUF ID 00h XXh 0000h XXh ACC=Manufacturer Id Read Manufacturer identifier READ DEVICE ID1 00h XXh 0001h XXh ACC= Device Id 1 Read Device identifier 1 READ DEVICE ID2 00h XXh 0002h XXh ACC=Device Id 2 Read Device identifier 2 READ DEVICE ID3 00h XXh 0003h XXh ACC=Device Id 3 Read Device identifier 3 ERASE BLOCK 01h XXh PROGRAM DATA BYTE ERASE BOOT VECTOR 02h Byte value to program PROGRAM SSB 05h XXh PROGRAM BSB 06h DPH=00h Erase block 0 DPH=20h Erase block 1 DPH=40h 00h ACC=DPH Erase block 2 DPH=80h Erase block 3 DPH=C0h Erase block 4 Address of byte to program ACC=0 : DONE 04h XXh XXh XXh ACC=FCh New BSB value DPH=00h DPL=00h DPH=00h DPL=01h DPH=00h DPL=10h DPH=00h DPL=11h 00h ACC= SSB value Program one Data Byte in user flash Erase Software boot vector and boot status byte.

Remark: number of bytes to program is limited such as the Flash write remains in a single 128bytes page. Hence, when ACC is 128, valid values of DPL are 00h, or, 80h.
