If one block is part of USI and other not, they might not be the same
I2C blocks, even if interface is similar. If they were the same or even
functionally the same, they would have the same clock inputs. However
user manual also suggests that there is only one clock, not two (for
both cases), so they could be functionally equivalent but then number of
clocks looks incorrect.
