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 PIC12F510, the register file is composed of 10
Special Function Registers, 6 General Purpose
Registers and 32 General Purpose Registers accessed
by banking (see Figure 4-2).
For the PIC16F506, the register file is composed of 13
Special Function Registers, 3 General Purpose
Registers and 64 General Purpose Registers accessed
by banking (see Figure 4-3).
4.2.1
GENERAL PURPOSE REGISTER
FILE
The General Purpose Register file is accessed either
directly or indirectly through the File Select Register
(FSR). See
Section 4.8 “Indirect Data Addressing:
INDF and FSR Registers”
.
