6.3.4
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 6-1 and Table 6-2.

functions. The reset and interrupt registers are
Registers related to the operation of a peripheral feature
The SFRs can be classified into two sets: those associ-
ated with the “core” device functionality (ALU, Resets
and interrupts) and those related to the peripheral
described in their respective chapters, while the ALU’s
STATUS register is described later in this section.
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.
