Anyone has some more information on the different modes(packet mode, analog mode, initialization, reset to analog mode) on the joystick?

All I found so far is:

I also found some adi.cpp from Linux with the activation sequence.

After which delay does it reset back to analog mode?
And does it send a special packet when it receives the digital activation sequence?

Edit: adi.c is at https://github.com/torvalds/linux/blob/master … /joystick/adi.c
