2.2.1
GENERAL PURPOSE REGISTER
FILE
The register file is organized as 128 x 8 bits in the
PIC16(L)F720, 256 x 8 bits in the PIC16(L)F721. Each
register is accessed either directly or indirectly through
the File Select Register (FSR), (Refer to Section 2.5
“Indirect Addressing, INDF and FSR Registers”).
2.2.2 SPECIAL FUNCTION REGISTERS
The Special Function Registers are registers used by
the CPU and peripheral functions for controlling the
desired operation of the device (refer to Table 2-2).
These registers are static RAM.
The Special Function 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.
