Program 5 [10 points] 8 DIP switches are connected to Port A pins (PA7-PA0). The settings on these 8 DIP switches represent a signed 8-bit number. Another 8 DIP switches are connected to Port B pins (PB7-PB0). These represent another 8-bit signed number. 8 LEDs are connected to Port T pins (PT7 - PT0). One extra LED is connected to Port M pin 0 (PMO). This last LED will be used as an overflow indicator. Write an assembly program that will continuously read the 2 numbers, add them, & display the result on the 8 LEDs on PT7-PTO. If the result overflowed, then turn on the overflow LED. Otherwise, turn it OFF. Lookup all the needed I/O registers and use their label names in your code. Assume you have header file included in your code. 4₁. WYPTO WPT7
