4.2
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 PIC16F526. See Figure 4-1
for details.
The PIC16F526 register file is composed of 16 Special
Function Registers and 67 General Purpose Registers.

4.2.1
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”.
4.2.2
The Special Function Registers (SFRs) are registers
used by the CPU and peripheral functions to control the
operation of the device (Table 4-1).
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.
