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 4-3). These reg-
isters are static RAM.
TABLE 4-3:
Address
Legend
— = unimplemented bits, read as ‘0’ but cannot be overwritten
r = reserved bits, default is POR value and should not be overwritten with any value
Reserved indicates reserved register and should not be overwritten with any value
* indicates registers that can be addressed from either bank

The special registers are classified into two sets.
Special registers associated with the “core” functions
are described in this section. Those registers related to
the operation of the peripheral features are described
in the section specific to that peripheral.
