Thanks for the correction - I just looked at the pretty picture and, not
seeing PWM among all the other coloure blobs, thought it wasn't available.

Does this mean that, if I put 5v on pin 1 I'll see 3.3v on pin 3, but the
reverse doesn't happen?

Yeah, I know I should Read The Fine Manual but I've got a few other
things (with deadlines attached) on my plate right now.
