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 4-1). These
registers are static RAM.
The special registers can be classied into two sets
(core and peripheral). The special function registers
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.

Note 1: Other (non power-up) resets include MCLR reset, Brown-out Reset and Watchdog Timer Reset during
normal operation.
Note 2: IRP & RPI bits are reserved, always maintain these bits clear.
