4.2

Data Memory (SRAM and SFRs)

Data memory is composed of registers or bytes of

SRAM. 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 are registers used by

the CPU and peripheral functions for controlling

desired operations of the PIC16F570. See Section 4.3

“STATUS Register” for details.

4.2.1

GENERAL PURPOSE REGISTER

FILE

The General Purpose Register file is accessed directly

or indirectly. See Section 4.8 “Direct and Indirect

Addressing”.

4.2.2

SPECIAL FUNCTION REGISTERS

The Special Function Registers (SFRs) are registers

used by the CPU and peripheral functions to control the

operation of the device (Section 4.3 “STATUS

The Special Function Registers can be classified into

two sets. The Special Function Registers associated

with the “core” functions are described in this section.

Those related to the operation of the peripheral

features are described in the section for each

peripheral feature.
