Write and assemble a program to toggle all the bits of PORTA, PORTB, and PORTC continuously by sending $55 and $AA to these ports. Put a time delay between the "on" and "off" states. Then using the simulator, single-step through the program and examine the ports. Do not single-step through the time delay call.

Using a simulator, write a program to get a byte of data from PORTB and send it to PORTA and PORTC. Also, give a copy of it to registers R20, R21, and R22. Single-step the program and examine the ports and registers.
