4.2.2
The Special Function Registers are registers used by
the CPU and peripheral modules for controlling the
desired operation of the device. These registers are
implemented as static RAM.

The special function registers can be classified into two
sets (core and peripheral). The registers associated
with the “core” functions are described in this section
and those related to the operation of the peripheral fea-
tures are described in the section of that peripheral fea-
ture.
