PIC16C62X  
4.2.2  
SPECIAL FUNCTION REGISTERS  
The special registers can be classified 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.  
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.

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.
