5.3.4
The Special Function Registers (SFRs) are registers
used by the CPU and peripheral modules for controlling
the desired operation of the device. These registers are
implemented as static RAM. SFRs start at the top of
data memory (FFFh) and extend downward to occupy
the top half of Bank 15 (F80h to FFFh). A list of these
registers is given in Table 5-1 and Table 5-2.
The SFRs can be classified into two sets: those
associated with the “core” device functionality (ALU,
Resets and interrupts) and those related to the
TABLE 5-1:

Registers available only on PIC18F4X8X devices; otherwise, the registers read as ‘0’.
When any TX_ENn bit in RX_TX_SELn is set, then the corresponding bit in this register has transmit properties.
This is not a physical register.

peripheral functions. The reset and interrupt registers
are described in their respective chapters, while the
ALU’s STATUS register is described later in this
section. Registers related to the operation of a
peripheral feature are described in the chapter for that
peripheral.
The SFRs are typically distributed among the
peripherals whose functions they control. Unused SFR
locations are unimplemented and read as ‘0’s.
