Aladin dive computer uses a CPU in uPD75308 family made by NEC. My friend told me that in an old Aladin Pro (without PC communicating function) he actually found uPD75308 on the board inside the Aladin. Therefore, I suspect that current models of Aladins also use the same family of CPU, more specifically, uPD75316.
uPD75316 is a four bits CPU and has two separate memory spaces of ROM (program memory; 16256 words x 8 bits) and RAM (data memory; 1024 words x 4bits). I/O ports and CPU registers are mapped to RAM. And for PC communicating function I think Aladin has an SRAM (2048 words x 8 bits) connected to I/O port outside of the CPU. All the contents but the last 8 bytes of this SRAM are sent to PC when Aladin changes its mode from [logbook] to [logbook1] (by user touching moisten fingers).
Note: A copy of the datasheet uPD75308
DataTalk can do the following:
This document is devoted to explain how DataTalk communicates with Aladin and does the functions (1) and (2) above.
Aladin and PC (or MemoMouse) are connected by RS232C protocol logically. Physically, however, since Aladin has only two pins, one signal line (connected to the "minus" contact of Aladin) is used to carry signals for both directions. Note: The other line that is connected to the "base" contact of Aladin is the signal ground.
Aladin sends 2050 bytes of data to PC (or MemoMouse) at
19200 baud, 8 bits, No parity and 1 stopbit,when either of the following condition is met:
After sending 2050 bytes of data, Aladin changes its input/output serial port settings to
4800 baud, 8 bits, No parity and 1 stopbit,and wait for
0x55, 0xdd, 0x33 (three bytes sequence).If Aladin successfully received the byte pattern, it responds to the sequence by sending a byte 0x3f (the '?' character) to PC (or MemoMouse), and then it enters to "Interpreter Mode", which is explained in the next section.
If the sequence is not received in a certain (very short) period of time Aladin goes into 1st logbook data display.
First, please note that all the bytes on the serial line are bit reversed, i.e., if
received/sent bit order from Aladin: b0 b1 b2 b3 b4 b5 b6 b7then
ordinary bit order of PC: b7 b6 b5 b4 b3 b2 b1 b0.So we must rearrange every received byte before proceeding further data processing. And similarly, we must do so to every byte before sending to Aladin.
In this interpreter mode, Aladin does the following:
(1) Receive one byte from PC (or MemoMouse).
(2) Execute the received byte. (If the byte is "EXIT (0xe7)" then
Aladin exits from "Interpreter Mode" and goes into 1st
logbook data display.)
(3) If there are some return value(s) after execution, send the
byte(s) to PC (or MemoMouse).
(4) Send a byte 0x84 (= bit reverse of 0x21, the ASCII '!')
to PC (or MemoMouse).
(5) Go to step (1).
In order to understand the mechanism of how Aladin executes received bytes, we introduce a model of an assembly language with a virtual CPU explained below.
The virtual CPU is a 4-bits CPU, and has only one index register.
+--------+--------+
Index register HL : | H | L |
+--------+--------+
The register HL has 8 bits width, and higher nibble is called 'H' and lower 'L'.
The memory map for this virtual CPU is the same to the real data memory map of 4-bits CPU (uPD75316) of Aladin. Some addresses have special meanings to some CPU instructions: We assign a symbol to each of these addresses in order to simplify the explanation.
+--------+--------+
Y : | 0x011 | 0x010 |
+--------+--------+
+--------+--------+
A : | 0x013 | 0x012 |
+--------+--------+
+--------+
DP : | 0x014 |
+--------+
+--------+--------+
BR : | 0x015 | 0x014 |
+--------+--------+
Note: The CPU is 4-bits and big-endian, i.e., every address can hold 4 bits and every byte (8 bits) is stored in even address (higher nibble is located in higher address).
Next is the table of instruction set of the virtual CPU. Detailed explanation follows.

================================================
LD H,#n4
Load the immediate 4 bits value n4 = I3:I2:I1:I0 to register H.
LD L,#n4
Load the immediate 4 bits value n4 = I3:I2:I1:I0 to register L.
PRINT (HL+)
Returns the 4 bits content of the address pointed by index
register HL. The return value is sent to PC (or MemoMouse)
as an 8 bits value
I3 I2 I1 I0 0 1 1 0
where I3:I2:I1:I0 is the content of the address.
After the value was sent, the index register HL is incremented
by 1.
PRINT (DP:HL+)
Returns the 4 bits content of the address designated by index
register HL and memory location DP (0x0014). The address is
calculated as
(DP << 8) + HL
The return value is sent to PC (or MemoMouse) as an 8 bits value
I3 I2 I1 I0 0 1 1 0
where I3:I2:I1:I0 is the content of the address.
After the value was sent, the index register HL is incremented
by 1. (Note: If index register HL overflows, it just becomes
zero and makes no influence to the content of DP.)
ST (HL+),#n4
Stores the immediate 4 bits value n4 = I3:I2:I1:I0 to the address
pointed by index register HL.
After storing the 4 bits, the index register HL is incremented
by 1.
ST (DP:HL+),#n4
Stores the immediate 4 bits value n4 = I3:I2:I1:I0 to the address
designated by index register HL and memory location DP (0x0014).
The address is calculated as
(DP << 8) + HL
After storing the 4 bits, the index register HL is incremented
by 1. (Note: If index register HL overflows, it just becomes
zero and makes no influence to the content of DP.)
OUT (BR:Y),A
Output a byte (8 bits) to the SRAM connected to I/O port.
The address in SRAM is calculated as
(BR & 0x0e) << 7 + Y
and the byte to output is the content of memory location A.
The value of BR should be in the form
BR = 0 0 1 0 I2 I1 I0 0
i.e., higher nibble must be 0x2, and lsb of the byte must be zero.
IN A,(BR:Y)
Input a byte (8 bits) from the SRAM connected to I/O port.
The address in SRAM is calculated as
(BR & 0x0e) << 7 + Y.
The value of BR should be in the form
BR = 0 0 1 0 I2 I1 I0 0
i.e., higher nibble must be 0x2, and lsb of the byte must be zero.
The input byte is stored at memory location A. And also,
the input byte is sent to PC (or MemoMouse) as two bytes
sequence. First, lower nibble I3:I2:I1:I0 is sent to PC (or
MemoMouse) as a byte
I3 I2 I1 I0 0 1 1 0
and next, higher nibble I7:I6:I5:I4 is sent to PC (or MemoMouse)
as a byte
I7 I6 I5 I4 0 1 1 0
EXIT
Exit from "Interpreter Mode" and go to "1st logbook" display.
NOP
Do nothing. (This opcode is used by "WakeUp" function of DataTalk
to detect whether Aladin is in "Interpreter Mode" or not.)
There are special addresses in data memory of Aladin. If you change some contents of these addresses you can change the behavior of Aladin. The following are the addresses I know so far.
address size (bits) description
------------------------------------------------------------------------------
0x174 4 bit 3: always 1
bit 2: Unit (0: Metric, 1: Imperial)
bit 1: always 0
bit 0: always 0

0x2e2 8 Breath warning sensitivity (Air series only).
Ranges are from 0x19 (insensitive) to 0x61 (sensitive).
The value is the same to the content of 0x7eb in
Aladin download.
0x300 8 Aladin selftest status for DataTalk for DOS.
0x300 == 0 : Service necessary.
!= 0 : Aladin is OK.
Note: MemoMouse or DataTalk for Windows seems not to
use this info anymore.
0x31e 4 bit 3: always 0
bit 2: always 0
bit 1: Beep (0: Off, 1: On)
bit 0: Unit (0: Metric, 1: Imperial)
0x31f 4 Constant (0).
0x329 4 Maximum O2 partial pressure ppO2 (Aladin O2 only)
[0x329] * 0.05 + 1.2 (bar)
Warning! All Aladin Nitroxen but O2 store this
information in a different place (0x32b).
0x32b 4 Maximum O2 partial pressure ppO2 (All Aladin Nitroxen
but O2 only)
[0x32b] * 0.05 + 1.2 (bar)
Warning! Aladin O2 store this information in a
different place (0x329).
0x349 4 Premix reset after XX hours. (Aladin O2 only)
The value is the same to the higher nibble of address
0x7d3 in Aladin download.
0x350 4 Maximum of vvO2 and SCR sensitivity (Aladin O2 only)
The value is the same to the higher nibble of address
0x7d2 in Aladin download.
------------------------------------------------------------------------------
All the following examples except Example 6 are actual sequences that Uwatec softwares (DOS or Windows versions of DataTalk) send to Aladin. There seems some "dead code" or unnecessary parts in the sequences but I recorded them here as they are.
