Each block (Program Memory and Data Memory) has its own bus, so that concurrent access can occur. Additional information on device memory may be found in the PICmicro Mid-Range MCU Family Reference Manual, (DS33023). 2.1 Program Memory Organization The PIC16C717/770/771 devices have a 13-bit pro- gram counter capable of addressing an 8K x 14 pro- gram memory space. The PIC16C717 and the PIC16C770 have 2K x 14 words of program memory. The PIC16C771 has 4K x 14 words of program mem- ory. Accessing a location above the physically imple- mented address will cause a wrap-around. The RESET vector is at 0000h and the interrupt vector is at 0004h. FIGURE 2-1: PROGRAM MEMORY MAP AND STACK OF THE PIC16C717 AND PIC16C770 FIGURE 2-2: PROGRAM MEMORY MAP AND STACK OF THE PIC16C771 2.2 Data Memory Organization The data memory is partitioned into multiple banks, which contain the General Purpose Registers and the Special Function Registers. Bits RP1 and RP0 are the bank select bits. = 00 Bank0 = 01 Bank1 = 10 Bank2 = 11 Bank3 Each bank extends up to 7Fh (128 bytes). The lower locations of each bank are reserved for the Special Function Registers. Above the Special Function Regis- ters are General Purpose Registers, implemented as static RAM. All implemented banks contain special function registers. Some frequently used special func- tion registers from one bank are mirrored in another bank for code reduction and quicker access. 2.2.1 GENERAL PURPOSE REGISTER FILE The register file can be accessed either directly, or indi- rectly, through the File Select Register FSR.
