Sorry, one more point, that I raised in the original mail yesterday and 
that I forgot about, when replying today:

In other words, I don't see where voltages are compared to select the 
minimum to be used for .on_vsel. Instead, it seems, .on_vsel is always set 
to the new value, and, if it is also higher then the old .dvs_vsel value, 
.dvs_vsel is _also_ set to the new voltage, in which case they become 
equal. Is this the intended behaviour?

Thanks
