Program Memory Organization
For The PIC16F505
The PIC16F505 device has a 11-bit Program Counter
(PC) capable of addressing a 2K x 12 program memory
space.
The 1K x 12 (0000h-03FFh) for the PIC16F505 are
physically
implemented.
Refer
to
Accessing a location above this boundary will cause a
wrap-around within the first 1K x 12 space. The
effective Reset vector is at 0000h (see Figure 4-2).
Location
03FFh
contains
the
internal
oscillator
calibration
value.
This
value
should
never
be
overwritten.

Data Memory Organization
Data memory is composed of registers or bytes of
RAM. Therefore, data memory for a device is specified
by its register file. The register file is divided into two
functional groups: Special Function Registers (SFR)
and General Purpose Registers (GPR).
The Special Function Registers include the TMR0
register, the Program Counter (PCL), the STATUS
register, the I/O registers (ports) and the File Select
Register (FSR). In addition, Special Function Registers
are used to control the I/O port configuration and
prescaler options.
The General Purpose Registers are used for data and
control information under command of the instructions.
For the PIC12F508/509, the register file is composed of
7 Special Function Registers, 9 General Purpose
Registers and 16 or 32 General Purpose Registers
accessed by banking (see Figure 4-3 and Figure 4-4).
For the PIC16F505, the register file is composed of 8
Special Function Registers, 8 General Purpose
Registers and 64 General Purpose Registers accessed
by banking (Figure 4-5).
4.3.1
GENERAL PURPOSE REGISTER
FILE
The General Purpose Register file is accessed, either
directly or indirectly, through the File Select Register
(FSR). See Section 4.9 “Indirect Data Addressing:
