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 and
General Purpose Registers.
The Special Function Registers include the TMR0 reg-
ister, the Program Counter (PC), the Status Register,
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 PIC16C54, PIC16CR54, PIC16C56 and
PIC16CR56, the register file is composed of 7 Special
Function Registers and 25 General Purpose Registers
(Figure 4-4).
For the PIC16C55, the register file is composed of 8
Special Function Registers and 24 General Purpose
Registers.
For the PIC16C57 and PIC16CR57, the register file is
composed of 8 Special Function Registers, 24 General
Purpose Registers and up to 48 additional General
Purpose Registers that may be addressed using a
banking scheme (Figure 4-5).
For the PIC16C58 and PIC16CR58, the register file is
composed of 7 Special Function Registers, 25 General
Purpose Registers and up to 48 additional General
Purpose Registers that may be addressed using a
banking scheme (Figure 4-6).
4.2.1
GENERAL PURPOSE REGISTER FILE
The register file is accessed either directly or indirectly
through the File Select Register (FSR). The FSR Reg-
ister is described in Section 4.7.
