MEMORY ORGANIZATION
3.1
Program Memory Organization
The PIC16F62X has a 13-bit program counter capable
of addressing an 8K x 14 program memory space. Only
the first 1K x 14 (0000h - 03FFh) for the PIC16F627
and 2K x 14 (0000h - 07FFh) for the PIC16F628 are
physically implemented. Accessing a location above
these boundaries will cause a wrap-around within the
first 1K x 14 space (PIC16F627) or 2K x 14 space
(PIC16F628). The RESET vector is at 0000h and the
interrupt vector is at 0004h (Figure 3-1).

AND STACK
3.2
Data Memory Organization
The data memory (Figure 3-2) is partitioned into four
the Special Function Registers (SFR). The SFR’s are
located in the first 32 locations of each Bank. Register
locations 20-7Fh, A0h-FFh, 120h-14Fh, 170h-17Fh
and
1F0h-1FFh
are
general
purpose
registers
implemented as static RAM.
The Table below lists how to access the four banks of
registers:
Addresses F0h-FFh, 170h-17Fh and 1F0h-1FFh are
implemented as common RAM and mapped back to
addresses 70h-7Fh.
3.2.1
GENERAL PURPOSE REGISTER
FILE
The register file is organized as 224 x 8 in the
PIC16F62X. Each is accessed either directly or
indirectly through the File Select Register FSR (See
