Cannot use pinMode, digitalRead, digitalWrite, and delay. can you also show the board setup

Part 5 - Putting Everything Together Write an Arduino program to read the state of PK2, output this state on PDO, and output the complement of this state on PE3. Write the program to minimize the time delay between a change on PK2 reflecting onto PDO and PE3. Attach a button to PK2, and an LED (with a series resistor) to PDO
