Yep, that's what it does. It's called the PI/T (parallel
interface/timer). Application note AN-854 describes using it for
printer interfacing and includes some sample code. There's also an AN975
that talks about the interrupt controlling capabilities of the '230 and
the 68901 and has register maps.

Also, if 68681 code is needed, I believe the MFC3 card for the Amiga
uses the '681, and the Amiga port has a driver for it.
