Note: The external RC oscillation frequencies shown in

external RC oscillation frequencies generated by the same
circuit design may be not the same. Because there are variations in the resistance and capacitance due to the tolerance of external R and C components. The parasitic
capacitance difference due to the different wiring length
and layout may change the external RC oscillation frequencies.

8. MEMORY ORGANIZATION
HMS87C1X04B/08B/16B
The HMS87C1X04B/08B/16B has separate address spaces for
Program memory and Data Memory. The Program memory can
only be read, not written to. It can be up to 4K /8K /16K bytes of
8.1 Registers
This device has six registers that are the Program Counter (PC),
a 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.

Y
SP
PCLPCH
PSW
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.
Y
A
Two 8-bit Registers can be used as a “YA” 16-bit Register
Figure 8-2 Configuration of YA 16-bit Register
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 extremely 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.
Stack Pointer: The Stack Pointer is an 8-bit register used for occurrence interrupts and calling out subroutines. Stack Pointer
identifies the location in the stack to be accessed (save or restore).

Program memory. The Data memory can be read and written to
up to 448 bytes including the stack area.
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 stack can be located at any position within 00
to BFH of the
H
internal data memory. The SP is not initialized by hardware, requiring to write the initial value (the location with which the use
of the stack starts) by using the initialization routine. Normally,
the initial value of “BF
15 087
” is used.
H
Stack Address (00

Hardware fixed
~ BFH)

SP
Note: The Stack Pointer must be initialized by software because its value is undefined after RESET.
Example: To initialize the SP
LDX #0BFH
TXSP ; SP ← BFH
Program Counter: The Program Counter is a 16-bit wide which
consists of two 8-bit registers, PCH and PCL. This counter indicates the address of the next instruction to be executed. In reset
state, the program counter has reset routine address (PC
PC
:0FEH).
L
:0FFH,
H
Program Status Word: The Program Status Word (PSW) contains several bits that reflect the current state of the CPU. The
PSW is described in Figure 8-3 . It contains the Negative flag, the
Overflow flag, Direct page select flag, the Break flag, the Half
Carry (for BCD operation), the Interrupt enable flag, the Zero
flag, and the Carry flag.
[Carry flag C]
This flag stores any carry or borrow from the ALU of CPU after
an arithmetic operation and is also changed by the Shift Instruction or Rotate Instruction.
[Zero flag Z]
This flag is set when the result of an arithmetic operation or data
transfer is “0” and is cleared by any other result.

[Interrupt disable flag I]
This flag enables/disables all interrupts except interrupt caused
by Reset or software BRK instruction. All interrupts are disabled
when cleared to “0”. This flag immediately becomes “0” when an
interrupt is served. It is set by the EI instruction and cleared by
the DI instruction.
[Half carry flag H]
After operation, this is set when there is a carry from bit 3 of ALU
or there is no borrow from bit 4 of ALU. This bit can not be set
or cleared except CLRV instruction with Overflow flag (V).
[Break flag B]
This flag is set by software BRK instruction to distinguish BRK
from TCALL instruction with the same vector address.
[Direct page select flag G]
INTERRUPT ENABLE FLAG
HALF CARRY FLAG RECEIVES
CARRY OUT FROM BIT 1 OF
ADDITION OPERLANDS
This flag assigned direct page for direct addressing mode. In the
direct addressing mode, addressing area is within zero page 00
to FFH when this flag is “0”. If it is set to “1”, addressing area is
100H to 1FFH.
It is set by SETG instruction, and cleared by CLRG instruction.
[Overflow flag V]
This flag is set to “1” when an overflow occurs as the result of an
arithmetic operation involving signs. An overflow occurs when
the result of an addition or subtraction exceeds +127(7F
) or -
H
128(80H). The CLRV instruction clears the overflow flag. There
is no set instruction. When the BIT instruction is executed, bit 6
of memory is copied to this flag.
[Negative flag N]
This flag is set to match the sign bit (bit 7) status of the result of
a data or arithmetic operation. When the BIT instruction is executed, bit 7 of memory is copied to this flag.

24 SEP. 2004 Ver 1.03
8.2 Program Memory
A 16-bit program counter is capable of addressing up to 64K
bytes, but these devices have 4K/8K/16K bytes program memory
space only physically implemented. Accessing a location above
will cause a wrap-around to 0000H.
FFFF
H
Figure 8-4 , shows a map of Program Memory. After reset, the
CPU begins execution from reset vector which is stored in address FFFEH and FFFFH as shown in Figure 8-5 .
As shown in Figure 8-4 , each area is assigned a fixed location in
Program Memory. Program Memory area contains the user program.

Figure 8-4 Program Memory Map
Page Call (PCALL) area contains subroutine program to reduce
program byte length by using 2 bytes PCALL instead of 3 bytes
CALL instruction. If it is frequently called, it is more useful to
save program byte length.
Table Call (TCALL) causes the CPU to jump to each TCALL address, where it commences the execution of the service routine.
The Table Call service area spaces 2-byte for every TCALL:
0FFC0
for TCALL15, 0FFC2H for TCALL14, etc., as shown in
H
Figure 8-6 .
The interrupt causes the CPU to jump to specific location, where
it commences the execution of the service routine. The External
interrupt 0, for example, is assigned to location 0FFFA
. The in-
H
terrupt service locations spaces 2-byte interval: 0FFF8H and
0FFF9H for External Interrupt 1, 0FFFAH and 0FFFBH for External Interrupt 0, etc.
As for the area from 0FF00H to 0FFFFH, if any area of them is not
going to be used, its service location is available as general purpose Program Memory.
