Hmm... In that case, I'm completely stumped. And I think there has to be
an error in the logic diagrams of PB5 and PB7 (Figures 41 and 43)
because they seem to show that the output buffer will only be enabled if
DDBn is 0 or SPIEN is 1, which can't be right, because DDBn=0 configures
a pin as an input. All the other diagrams show the output buffer being
enabled when DDBn is 1.
