Program Memory
Ø
The HMS38112/39112 can incorporate maximum 1,024 words (64 words 16
pages 8bits) for program memory. Program counter PC (A0~A5) and page
address register (A6~A9) are used to address the whole area of program memory
having an instruction (8bits) to be next executed.
The program memory consists of 64 words on each page, and thus each page
can hold up to 64 steps of instructions.
The program memory is composed as shown below.

Chapter 3. Architecture
Address Register
The following registers are used to address the ROM.
• Page address register (PA) :
Holds ROM's page number (0~Fh) to be addressed.
• Page buffer register (PB) :
Value of PB is loaded by an LPBI command when newly addressing a page.
Then it is shifted into the PA when rightly executing a branch instruction (BR)
and a subroutine call (CAL).
• Program counter (PC) :
Available for addressing word on each page.
• Stack register (SR) :
Stores returned-word address in the subroutine call mode.
(1) Page address register and page buffer register :
Address one of pages #0 to #15 in the EPROM by the 4-bit binary counter.
Unlike the program counter, the page address register is usually unchanged so
that the program will repeat on the same page unless a page changing command
is issued. To change the page address, take two steps such as (1) writing in the
page buffer what page to jump (execution of LPBI) and (2) execution of BR or CAL,
because instruction code is of eight bits so that page and word can not be specified
at the same time.
In case a return instruction (RTN) is executed within the subroutine that has been
called in the other page, the page address will be changed at the same time.
(2) Program counter :
This 6-bit binary counter increments for each fetch to address a word in the
currently addressed page having an instruction to be next executed.
For easier programming, at turning on the power, the program counter is
reset to the zero location. The PA is also set to "0". Then the program
counter specifies the next address in random sequence.
When BR, CAL or RTN instructions are decoded, the switches on each step
are turned off not to update the address. Then, for BR or CAL, address
data are taken in from the instruction operands (a0 to a5), or for RTN, and
address is fetched from stack register No. 1.
(3) Stack register :
This stack register provides two stages each for the program counter (6bits)
and the page address register (4bits) so that subroutine nesting can be
made on two levels.

Y-register (Y)
Y-register has 4 bits. It operates as a data pointer or a general-purpose register.
Y-register specifies an address (a0~a3) in a page of data memory, as well as it
is used to specify an output port. Further it is used to specify a mode of carrier
signal outputted from the REMOUT port. It can also be treated as a generalpurpose register on a program.

Accumulator (ACC)
The 4-bit register for holding data and calculation results.
Arithmetic and Logic Unit (ALU)
In this unit, 4bits of adder/comparator are connected in parallel as it's main
components and they are combined with status latch and status logic (flag.)
(1) Operation circuit (ALU) :
The adder/comparator serves fundamentally for full addition and data
comparison. It executes subtraction by making a complement by processing
an inversed output of ACC (ACC+1)
(2) Status logic :
This is to bring an ST, or flag to control the flow of a program. It occurs when
a specified instruction is executed in three cases such as overflow or underflow
in operation and two inputs unequal.
State Counter (SC)
A fundamental machine cycle timing chart is shown below. Every instruction is
one byte length. Its execution time is the same. Execution of one instruction
takes 6 clocks for fetch cycle and 6 clocks for execute cycle (12 clocks in total).
Virtually these two cycles proceed simultaneously, and thus it is apparently
completed in 6 clocks (one machine cycle). Exceptionally BR, CAL and RTN
instructions is normal execution time since they change an addressing sequentially.
Therefore, the next instruction is prefetched so that its execution is completed
within the fetch cycle.

Reset Operation
HMS38112/39112 have three reset sources. One is a built-in Power-on reset circuit, another
is a built-in Low VDD Detection circuit, the other is the overflow of Watch Dog Timer
(WDT). All reset operations are internal in the HMS38112.
Built-in Power On Reset Circuit
HMS38112/39112 has a built-in Power-on reset circuit consisting of an about
1 Resistor and a 3pF Capacitor. When the Power-on reset pulse occurs,
system reset signal is latched and WDT is cleared. After the overflow time of WDT
(213 x System clock time), system reset signal is released.

Watch Dog Timer (WDT)
Watch dog timer is organized binary of 14 steps. The signal of fOSC/48 cycle comes
in the first step of WDT after WDT reset. If this counter was overflowed, reset
signal automatically come out so that internal circuit is initialized.
The overflow time is 8 6 213/fOSC (108.026ms at fOSC = 3.64MHz)
Normally, the binary counter must be reset before the overflow by using reset
instruction (WDTR), Power-on reset pulse or Low VDD detection pulse.

STOP Operation
Stop mode can be achieved by STOP instructions.
In stop mode :
1. Oscillator is stopped, the operating current is low.
2. Watch dog timer is reset, D0~D3 output and REMOUT output are "L" .
3. Part other than WDT, D0~D3 output and REMOUT output have a value before
come into stop mode.
Stop mode is released when one of K or R input is going to "L".
1. State of D0~D3 output and REMOUT output is return to state of before stop mode
is achieved.
Ø
2. After 210 System clock time for stable oscillating, first instruction start to operate.
3. In return to normal operation, WDT is counted from zero again.
But, at executing stop instruction, if one of K or R input is chosen to "L", stop instruction
is same to NOP instruction.

For some programs, normal sequential program execution can
be change.
A branch is conditionally implemented depending on the status
of results obtained by executing the previous instruction.
• Branch instruction is always conditional depending on the
status.
a. If the status is reset (logic 0), a branch instruction is not
rightly executed but the next instruction of the sequence is
executed.
b. If the status is set (logic 1), a branch instruction is executed
as follows.
• Branch is available in two types - short and long. The former
is for addressing in the current page and the latter for
addressing in the other page. Which type of branch to exeute
is decided according to the PB register. To execute a long
branch, data of the PB register should in advance be modified
to a desired page address through the LPBI instruction.

Note : PC actually has pseudo-random count against the next

• In a program, control is allowed to be transferred to a mutual
subroutine. Since a call instruction preserves the return
address, it is possible to call the subroutine from different
locations in a program, and the subroutine can return control
accurately to the address that is preserved by the use of the
call return instruction (RTN).
Such calling is always conditional depending on the status.
a. If the status is reset, call is not executed.
b. If the status is set, call is rightly executed.
The subroutine stack (SR) of three levels enables a subroutine
to be manipulated on three levels. Besides, a long call (to call
another page) can be executed on any level.
• For a long call, an LPBI instruction should be executed before
the CAL. When LPBI is omitted (and when PA=PB), a short
call (calling in the same page) is executed.

Chapter 5. Application
Guideline for S/W
1. All rams need to be initialized to zero in reset address for proper design.
2. Make the output ports `H` after reset.
3. Do not use WDTR instruction in subroutine.
4. Before reading the input port the waiting time should be more than 200uS.
5. To decrease current consumption, make the output port as high in normal routine except
for key scan strobe and STOP mode.
6. We recommend you do not use all 64 bytes in a page. You had better write ` BR $` in
unused area. This will help you prevent unusual operation of MCU.
7. Be careful not to use long call or branch (CALL,BL) with arithmetic manipulation.
If you want to use branch right after arithmetic manipulation, the long call or branch will be
against your intention.
ex)
LAR
; The value of R ports -> Accumulator
ALEI 14 ; Aõ14 : S = 1,
A 14 : S = 0
BL TRUE ; S is always 1 because BL is composed of LPBI and BR.
-------------- Fail
!
LAR
; The value of R ports -> Accumulator
ALEI 14 ; Aõ14 : S = 1,
A 14 : S = 0
BR TRUE ; When S is 1 Branch will occur. Otherwise Branch will not occur and
LAK
; next instruction will be operated.
-------------- Right

* note : the position of SW49~56 and SW57~64 in B/D is changed. The reference position is right.
* If you want to increase the remote controller valid distance, you try to disconnect R2 resistor
and lessen R1 resistor.
