Output port
* If the low level causes inactive state (LED turns off), an external pull-down resister is required.
Initial Configuration for OUTPUT PORT (LED Display Example)
The initial state of OUTPUT PORT is high-impedance (floating) state. It remains in its high-impedance
(floating) state during both reset (nRESET = Low) and the period from de-assertion of reset (nRESET =
High) to the first OUTPUT DATA packet received. To avoid this, either a pull-up or a pull-down resister
should be added externally to each pin of the OUTPUT PORT to ensure the inactive sate of the
corresponding pin during the high-impedance state.
