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 (PC), the STATUS regis-
ter, the I/O registers (ports) and the File Select Register
(FSR). In addition, Special Purpose 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 PIC16F54, the register file is composed of 7
Special Function Registers and 25 General Purpose
Registers (Figure 3-3).
For the PIC16F57, the register file is composed of 8
Special Function Registers, 8 General Purpose
Registers
and
64
additional
General
Purpose
Registers that may be addressed using a banking
For the PIC16F59, the register file is composed of 10
Special Function Registers, 6 General Purpose
Registers
and
128
additional
General
Purpose
Registers that may be addressed using a banking
3.2.1
GENERAL PURPOSE REGISTER
FILE
The register file is accessed either directly or indirectly
through the File Select Register (FSR). The FSR
register is described in Section 3.7 “Indirect Data
