The last chip I saw a datasheet for was the BM1385 from the S7. Everything after that we had to work off repair guides and reverse-engineer the rest.
On that note, do you or anyone know what the different modes are and how to set the ASIC in a particular mode?
I'm trying to put together a full schematic and usable (i.e. written in clear, technical English) and intend to share my work. Started with an S17e board that I have knocking about.
Thanks in advance.
