PIC16F684
2.2.1
The register file is organized as 128 x 8 in the
PIC16F684. 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 are registers used by
the CPU and peripheral functions for controlling the
desired operation of the device (see Table 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.
