PROJECTA. Write a program to receive an 8-bit input value from port A and display the input value on port B. B. Write a program such that when bit 0 of port C is cleared, all LEDs connected to Port A & B will start turning on one at a time beginning with RA 0. Note that the speed of lights togging can be about 50usec to 1 sec. Show how you calculate the delay. C. In this part you are about to design a simple calculator. In your design you must receive any two numbers from port A & port B (e.g., Num A & Num B) respectively and perform the following algebraic operation as stated in the table below:Rc1Rc0Operation0 0 ADD0 1 SUBTRACT1 0 DIVIDE1 1 MUTIPLYThe description of inputs and outputs are shown below: REG NAME BIT SIZE VALUE HOLDINGNEG REG 1 Set when results I negative. NODIV REG 1 Set if the result has a remainder. OVER FLOW REG1 If the result is larger than 16 bitsRESULT REG 16 Contains the final resultNUM A 8 Contains the 8-bit inputNUM B 8 Contains the 8-bit inputOPER REG 1 Determines the type of the operationHere is the schematic of your calculator with all its inputs and outputs. Example of operation:Input NUM A = 20H NUM B = 3H RC [0-1] = 000 (indicating ADD operation)Output NEG REG = 0 NODIVFLAG REG = 0 OVERFLOW REG = 0 NUMBER A REG = 20H NUMBER B REG = 3H OPER REG = 000 RESULT REGH = 23 RESULT REGL =
