Can the pins on the Arduino Mega Board labeled: TX3/Rx3, Tx2/RX2 .... be used as regular digital IO pins?

Can the pins on the Arduino Mega Board labeled: TX3/Rx3, Tx2/RX2 .... be used as regular digital IO pins?

Yes of course. Rx/Tx 1,2 & 3 = digital pins 19,18,17,16,15 & 14. Rx/Tx 0 remains as digital pins 0 & 1.
