Yes, there is a newer document called "HY46XX Application Notes
V4.0", here is the screenshot of models:

It's an upgraded version even if hardware is fully compatible, so (B)
means with and without "B".

Ah yes, I've started from edt,ft5x06.yaml and there it was indented that

Ah yes, it's true. If not specified it's simply not enabled, so I use

Oh yes! I didn't realize it was exactly in Hertz, 0x64 is 100, not only
