If sel is high, then a counter is output on the output pins and the bidirectional pins (data_o = counter_o = counter).
If sel is low, the bidirectional pins are mirrored to the output pins (data_o = data_i).
Set sel high and observe that the counter is output on the output pins (data_o) and the bidirectional pins (counter_o).
Set sel low and observe that the bidirectional pins are mirrored to the output pins (data_o = data_i).
