ADuC816
–23–
Reset initializes the stack pointer to location 07 hex and increments
it once to start from locations 08 hex which is also the first regis-
ter (R0) of register bank 1. Thus, if one is going to use more
than one register bank, the stack pointer should be initialized to an
area of RAM not used for data storage.
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 ADuC816 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
executions. 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 manipulated 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.
