The SFR space is mapped to the upper 128 bytes of internal data
memory space and accessed by direct addressing only. It provides
an interface between the CPU and all on-chip peripherals. A block
diagram showing the programming model of the ADuC824 via
the SFR area is shown in Figure 16. A complete SFR map is shown
in Figure 17.

OVERVIEW OF MCU-RELATED SFRs
Accumulator SFR
ACC is the Accumulator register and is used for math operations
including addition, subtraction, integer multiplication and division,
and Boolean bit manipulations. The mnemonics for accumulator-
specific instructions refer to the Accumulator as A.
B SFR
The B register is used with the ACC for multiplication and divi-
sion operations. For other instructions it can be treated as a
general-purpose scratchpad register.
Stack Pointer SFR
The SP register is the stack pointer and is used to hold an internal
RAM address that is called the
‘top of the stack.’
The SP register is
incremented before data is stored during PUSH and CALL execu-
tions. While the stack may reside anywhere in on-chip RAM, the
SP register is initialized to 07H after a reset. This causes the
stack to begin at location 08H.
Data Pointer
The Data Pointer is made up of three 8-bit registers, named
DPP (page byte), DPH (high byte), and DPL (low byte).
These are used to provide memory addresses for internal and
external code access and external data access. It may be ma-
nipulated as a 16-bit register (DPTR = DPH, DPL), although
INC DPTR instructions will automatically carry over to DPP, or
as three independent 8-bit registers (DPP, DPH, DPL).
Program Status Word SFR
The PSW register is the Program Status Word which contains
several bits reflecting the current status of the CPU as detailed in
Table I.
