Sorry for the delay. I've looked at the specification (
http://www.hitachi-eu.com/hel/ecg/products/micro/pdf/sh7751h.pdf ) but due
to lack of familiarity with these specifics, I can't really say for
definite that it's right or wrong. Can you a) provide a little more
explanation so I can be sure it's correct, and b) provide a ChangeLog entry
:-).

OTOH, I've CC'd Jesper who may also be able to tell me if it's good or not.
