Microchip Technology 

PIC12F635/PIC16F636/639

2.2.1 GENERAL PURPOSE REGISTER

The register file is organized as 64 x 8 for the

PIC12F635 and 128 x 8 for the PIC16F636/639. Each

register is accessed, either directly or indirectly,

through the File Select Register, FSR (see Section 2.4

“Indirect Addressing, INDF and FSR Registers”).

2.2.2 SPECIAL FUNCTION REGISTERS

The Special Function Registers (SFRs) are registers

used by the CPU and peripheral functions for controlling

the desired operation of the device (see Figure 2-1).

These registers are static RAM.

The special registers can be classified into two sets:

core and peripheral. The Special Function Registers

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

Those related to the operation of the peripheral

features are described in the section of that peripheral

feature.
