3.2.2
The Special Function Registers (FSR) 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.

Shaded cells = unimplemented or unused, – = unimplemented, read as ‘0’ (if applicable), x = unknown, u = unchanged
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.
These values are valid for PIC16F57. For the PIC16F54, the value on Reset is ‘111x xxxx’ and for MCLR and WDT
Reset, the value is ‘111u uuuu’.
Unimplemented bits are read as ‘0’s.
