It's a bit-banged synchronous serial interface, pretty much the same as
NES/SNES controllers. Tell it to get ready, then start toggling the
clock pin and data pin. IIRC there is a DATA and COMMAND serial line on
the PSX/PS2 interface, DATA being the controller-to-host connection and
COMMAND being host-to-controller. I can't remember if timing is
important. "Not too fast" I think ;-)
