4.2.2 SPECIAL FUNCTION REGISTERS
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.
PIC14000
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.
