3.2.2 SPECIAL FUNCTION REGISTERS
The SFRs are registers used by the CPU and Periph-
eral functions for controlling the desired operation of
the device (Table 3-1). These registers are static RAM.
The special registers can be classified into two sets
(core and peripheral). The SFRs 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.
