6.3.4 SPECIAL FUNCTION REGISTERS
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.
The main group of SFRs start at the top of data memory
(FFFh) and extend downward to occupy more than the
top half of Bank 15 (F60h to FFFh). These SFRs can
be classified into two sets: those associated with the
“core” device functionality (ALU, Resets and interrupts)
and those related to the 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 the peripheral features 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. A list of
SFRs is given in Table 6-3; a full description is provided
in Table 6-5.
