Recover Chip PIC16HV785 Hex

Recover Chip PIC16HV785 Hex include the content from both its eeprom and flash, belows we can introduce the program memory organization:

PROGRAM MEMORY ORGANIZATION

The PIC16F785/HV785 has a 13-bit program counter capable of addressing an 8k x 14 program memory space. Only the first 2k x 14 (0000h-07FFh) for the PIC16F785/HV785 is physically implemented. Accessing a location above these boundaries will cause a wrap around within the first 2k x 14 space. The Reset vector is at 0000h and the interrupt vector is at 0004h.

DATA MEMORY ORGANIZATION

The data memory is partitioned into four banks, which contain the General Purpose Registers (GPR) and the Special Function Registers (SFR). The Special Function Registers are located in the first 32 locations of each bank. Register locations 20h-7Fh in Bank 0 and A0h-BFh in Bank 1 are General Purpose Registers, implemented as static RAM.

The last sixteen register locations in Bank 1 (F0h-FFh), Bank 2 (170h-17Fh), and Bank 3 (1F0h-1FFh) point to addresses 70h-7Fh in Bank 0. All other RAM is unimplemented and returns ‘0’ when read.

PROGRAM MEMORY MAP AND STACK FOR THE PIC16F785/HV785

Seven address bits are required to access any location in a data memory bank which can also facilitate the process of IC Cloning. Two additional bits are required to access the four banks. When data memory is accessed directly, the seven Least Significant address bits are contained within the opcode and the two Most Significant bits are contained in the STATUS register for the purpose of recover chip PIC16HV785 Hex.

RP0 and RP1 bits of the STATUS register are the two Most Significant data memory address bits and are also known as the bank select bits. Table 2-1 lists how to access the four banks of registers.
