8. MEMORY ORGANIZATION
The HMS81004E/08E/16E/24E/32E has separate address
spaces for Program memory and Data Memory. Program
memory can only be read, not written to. It can be up to
32K bytes of Program memory. Data memory can be read
and written to up to 448 bytes including the stack area.
8.1 Registers
This device has six registers that are the Program Counter
(PC), an Accumulator (A), two index registers (X, Y), the
Stack Pointer (SP), and the Program Status Word (PSW).
The Program Counter consists of 16-bit register.
Figure 8-1 Configuration of Registers
Accumulator:
The Accumulator is the 8-bit general purpose register, used
for data operation such as transfer, temporary saving, and
conditional judgement, etc. The Accumulator can be used
as a 16-bit register with Y Register as shown below.
In the case of multiplication instruction, execute as a mul-
tiplier register. After multiplication operation, the lower 8-
bit of the result enters. (Y*A => YA). In the case of divi-
sion instruction, execute asthe lower 8-bitof dividend.Af-
ter division operation, quotient enters.

X, Y Registers:
In the addressing mode which uses these index registers,
the register contents are added to the specified address,
which becomes the actual address. These modes are ex-
tremely effective for referencing subroutine tables and
memory tables. The index registers also have increment,
decrement, comparison and data transfer functions, and
they can be used as simple accumulators.
• X Register
In the case of division instruction, execute as register.
• Y Register
In the case of 16-bit operation instruction, execute as the
upper 8-bit of YA. (16-bit accumulator). In the case of
multiplication instruction, execute as a multiplicand regis-
ter. After multiplication operation, the upper 8-bit of the
result enters. In the case of division instruction, execute as
the upper 8-bit of dividend. After division operation, re-
mains enters. Y register can be used as loop counter of con-
ditional branch command. (e.g.DBNE Y, rel)
Stack Pointer:
The Stack Pointer is an 8-bit register used for occurrence
interrupts, calling out subroutines and PUSH, POP, RETI,
RET instruction. Stack Pointer identifies the location in the
stack to be accessed (save or restore).
Generally, SP is automatically updated when a subroutine
call is executed or an interrupt is accepted. However, if it
is used in excess of the stack area permitted by the data
memory allocating configuration, the user-processed data
may be lost. The SP is post-decremented when a subrou-
tine call or a push instruction is executed, or when an inter-
rupt is accepted. The SP is pre-incremented when a return
or a pop instruction is executed.
The stack can be located at any position within 100Hto
1FFHof the internal data memory. The SP is not initialized
by hardware, requiring to write the initial value (the loca-
tion with which the use of the stack starts) by using the ini-
tialization routine. Normally, the initial value of "FFH" is
used.
