Aha! Yes, I had read the code wrongly, I figured the pmfs only wrote but
in fact there's a read/mask too. Thanks :)

Also, bit 0x2 is the input data, though it's only useful if "output
enable" is cleared (or it will just reflect the state of the outputs).

Yeah ok, I'll change/retest the patch during the week.

Thanks,
