The special function registers are registers used by the
CPU and Peripheral Modules 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 regis-
ters 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.
