MEMORY ORGANIZATION

2.1

Program Memory Organization

The PIC16F707/PIC16LF707 has a 13-bit program

counter capable of addressing an 8K x 14 program

memory space. The Reset vector is at 0000h and the

interrupt vector is at 0004h.

Data Memory Organization

The data memory is partitioned into multiple banks

which contain the General Purpose Registers (GPRs)

and the Special Function Registers (SFRs). Bits RP0

and RP1 are bank select bits.

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

Registers are the General Purpose Registers,

implemented as static RAM. All implemented banks

contain Special Function Registers. Some frequently

used Special Function 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 is organized as 363 x 8 bits. Each

the File Select Register (FSR), (Refer to Section 2.5

“Indirect Addressing, INDF and FSR Registers”).

2.2.2

SPECIAL FUNCTION REGISTERS

The Special Function Registers are registers used by

the CPU and peripheral functions for controlling the

desired operation of the device (refer to Table 2-2).

These registers are static RAM.

The Special Function Registers can be classified into

two sets: core and peripheral. The Special Function

Registers associated with the “core” are described in

this section. Those related to the operation of the

peripheral features are described in the section of that

peripheral feature.
