Data Memory (SRAM and FSRs)
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 reg-
ister, the Program Counter (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
GENERAL PURPOSE REGISTER
FILE
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
SPECIAL FUNCTION REGISTERS
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.
