PIC12F635/PIC16F636/639
2.2.1
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
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.
