IMPORTANT: Microcontroller with EEPROM Memory.The ID locations are addressed in the buffer at 4000h-4007h.It is recommended by Microchip that the user program the ID Locations as 11 1111 1000 bbbb’.The option of programming the 7 Least Significant Bits of each ID location is given. TheConfiguration word is located at buffer address 400Eh. Both the ID andConfiguration word may be set under Device Configure or from the abovementioned addresses in your data file.User Program memory is addressed in the buffer at 0000h-3FFFh.The Configuration word is located at buffer address 400Eh.EEPROM (Data Memory) is addressed in the buffer at 4200h-43FFh. Please noteonly the least significant byte of the EEPROM (Data Memory) section is actualEEPROM Data. The most signifcant byte should be set to 00h.FLASH(Program Memory) and EEPROM(Data Memory) can be protected by setting Secure options.Select ‘Flash’ to protect FLASH(Program Memory) only (0h-1FFFh) ‘F1′ to protect 1000h-1FFFh’F2’ to protect 1F00h-1FFFh ‘EE’ to protect EEPROM(Data Memory) ‘ALL’ to protect everything(‘Flash’ and ‘EE’ memory).The Device Sum command is updated from algorithm revision 1.24and it is to calculate Device checksum. The ‘Sum’ command generates the checksumcalculation as specified by Microchip. ‘
