Regarding Japanese signalling functionality for the BVEC_ATS plugin

I have noticed that certain Japanese routes utilizing BVEC_ATS (The Tohoku Shinkansen, to be specific) call out the [ATC] and [ATS-P] functionalities of the plugin. 
However, there are no guidelines provided on BVE Cornwall as far as I can tell.
Can someone tell me where to find proper guidelines regarding Japanese signalling? Thanks.

Can I clarify what you're asking please?

Some basic player info on ATC is here:

Odakyufan's driver documenatation is here:

If you're after the actual developer documentation, the best I can do for you is the attached file. This is Odakyufan's developer docs for the OdakyufanATS plugin.

The ATC implementation in BVEC_ATS is primarily Odakyufan's code, but with some changes submitted / requested by Midnightexpress1981 & F81_tec200 (The developers for the Tohoku Shinkansen).

Japanese signalling isn't really my forte, so I've essentially just made the behavioural changes asked for

That is exactly what I am after for, thanks.
The reason behind is: I am mainly developing and updating openBVE trains for Hong Kong (my home country), but is also developing Japanese trains and updating the routes to support the new signalling.
