SPECIAL FUNCTION REGISTERS
The Special Function Registers are registers used by
the CPU and peripheral functions to control the opera-
tion of the device (Table 4-1).
The Special Registers can be classified into two sets.
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 for each peripheral feature.

Legend: Shaded boxes = unimplemented or unused, – = unimplemented, read as ’0’ (if applicable)
x
= unknown, u = unchanged, q = see the tables in Section 7.7 for possible values.
Note 1:
The upper byte of the Program Counter is not directly accessible. See Section 4.5 for an explanation of how to access
these bits.
2: File address 07h is a General Purpose Register on the PIC16C54, PIC16CR54, PIC16C56, PIC16CR56, PIC16C58 and
PIC16CR58.
3: For the PIC16C54 and PIC16C55, the value on RESET is 111x xxxx and for MCLR and WDT Reset, the value is
