-      If input 0 is high, then a counter is output on the outputs and the bidirectional outputs. Otherwise the inputs are mirrored to the outputs.
+      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`).
