4.2.2
The Special Function Registers are registers used by
the CPU and Peripheral functions for controlling the
desired operation of the device (Table 4-1). 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” functions are
described in this section. Those related to the operation
of the peripheral features are described in the section
of that peripheral feature.
