but in practice, how did you get this data.
Are command codes SAA73xx ?
should they be read/written in the ATMEGA32?

they should be read/written in the ATMEGA32 - yes 100%
you make some mistake -
in line A2h, 42h, 00h, and next lines:
the command is A2h (see table 17 string "Write_parameter"). 42h is RAM memory address - see table 18 string "seq_control", and 00h is writting data.

in fact I didn't write down this command.
In practice in ARDUINO IDE how the code should be built ?

Reading this instruction is a waste of time, in fact the instruction is just a small problem, what really needs to be complete is the operation and details!

This control board is everywhere in China, cdm12.1 is very popular in China, especially a few years ago, you just need to buy a control board on Taobao,
and then modify the circuit to I2C directly connect to SAA7327!
There is no need for this MCU for DSA and I2C conversion! DSA is just to be compatible with old servo boards, and it takes longer to read TOC!
This HECD-019A is actually not very good, I have measured the RF signal, it is very poor, resulting in most cyrus cd8 is not working properly! I have changed the servo board on my Cyrus CD8 to my own design!

I know the JOSADUIO development and control boards, in fact I have the JOSAUDIO CDM and IDE controls, also the JOSAUDIO CDM12 SERVO. But in the case of the post, my project was born to be able to do what JOSAUDIO has developed. Using Arduino and thanking dxx573k for the help he is giving me, we could be able to make this mechanism combined with Arduino, "save" more medium and high-level CD players that could end up in the cellar or landfill. Retrieving the original check where i Digital servo processors e Compact Disc decoder with Integrated DAC of the SAA73xx series. I hope I was clear.
In the HECD-019A SERVO CD board, bypassing the Philips P87C58 Eprom, there are the pins and connectors to do all this.

the two files contain the video sequences and data of the movements of the mechanical and laser axes when the cd reader is switched on (power supply).
file RAR (Session Power.rar) with the pickup in position 0
file RAR (Session Power x axis not at 0 position.rar) with X axis not at 0 position
file RAR (Session Power.rar) with the pickup in position 0
file RAR (Session Power x axis not at 0 position.rar) with X axis not at 0 position
so these would be the initialization parameters of the mechanics ?
these should be written in the code or they are parameters stored inside the SAA73xx and therefore it is not necessary to write in the Atmega memory.
these should be written in the code in start up part. All command muust be written line by line.
The main task to start with is - to configure the bus and learn how to send commands to SAA and read the answear.
okay.
therefore have to write the code and enter the individual commands collected, send them one by one to the SAA and see the response.
the problem is now to write the code.
Ah ok.
And that philips OM5284 what is it for, does it take the place of the p87c58?
