Copy Binary from Locked Microprocessor PIC18F6520 from its flash and eeprom memory, then replicate the CONTENT to new Microontroller PIC18F6520 for the perfect cloning which is the completion of MCU cracking process;
Depending on the application, good programming practice may dictate that the value written to the memory should be verified against the original value. This should be used in applications where excessive writes can stress bits near the specification limit.
If a write is terminated by an unplanned event, such as loss of power or an unexpected Reset, the memory location just programmed should be verified and reprogrammed if needed. If the write operation is interrupted by a MCLR Reset or a WDT Time-out Reset during normal operation, the user can check the WRERR bit and rewrite the location(s) as needed.
The data EEPROM is a nonvolatile memory array, separate from the data RAM and program memory, that is used for long-term storage of program data when copy program from Microchip PIC12C671.
It is not directly mapped in either the register file or program memory space but is indirectly addressed through the
Special Function Registers (SFRs). The EEPROM is readable and writable during normal operation over the entire VDD range. Five SFRs are used to read and write to the data EEPROM as well as the program memory. They are:The data EEPROM allows byte read and write.
When interfacing to the data memory block, EEDATA holds the 8-bit data for read/write and the EEADR register holds the address of the EEPROM location being accessed. The EEPROM data memory is rated for high erase/write cycle endurance.
A byte write automatically erases the location and writes the new data (erase-before-write). The write time is controlled by an on-chip timer; it will vary with voltage and temperature as well as from chip to chip. Please refer to parameter D122 (Table 26-1 in Section 26.0 “Electrical Characteristics”) for exact limits before extract code from MCU PIC12LC671.
The EEADR register is used to address the data EEPROM for read and write operations. The 8-bit range of the register can address a memory range of 256 bytes (00h to FFh). Access to the data EEPROM is controlled by two registers: EECON1 and EECON2. These are the same registers which control access to the program memory and are used in a similar manner for the data EEPROM.
