3.2.2
The Special Function Registers (SFR) are registers
used by the CPU and peripheral functions to control the
operation of the device (Table 3-1).
The Special Function 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.

The upper byte of the Program Counter is not directly accessible. See Section 3.5 “Program Counter”
for an explanation of how to access these bits.
File address 07h is a General Purpose Register on the PIC16F54.
PIC16F54 only.
PIC16F57 only.
PIC16F59 only.
Unimplemented bits are read as ‘0’s.
File address 08h and 09h are General Purpose Registers on the PIC16F54 and PIC16F57.
