4.2
Data memory is composed of registers or bytes of
SRAM. Therefore, data memory for a device is speci-
fied 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 Low (PCL), the STATUS
register, the I/O register (port) and the File Select
Register (FSR). In addition, the EECON, EEDATA and
EEADR registers provide for interface with the Flash
data memory.
The PIC12F519 register file is composed of 10 Special
Function Registers and 41 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.
