Print first 2 Fib values (0, 1) before starting These are hard-coded since they are starting values...no calculations required Enter MainLoop Loop and call subroutines to calculate each subsequent value in the sequence Exit the loop once all single-digit values in the sequence have been printed USE 3 subroutines calcNextFib Uses R1 and R2 to calc next value in Fibonacci sequence printNum Outputs single-digit number to the display printCommaSpace Outputs a comma and a spaceCalculate all the single-digit Fibonacci numbers in order Start with the first 2 values in the sequence (0, 1) Calculate the next value by adding together the two largest values Print each number in the sequence With a comma and space after each No comma after the last number Use LC-3 I/O device to print number, commas, and spaces NO numbers printed using Trap Routine should check ddr, dsr , load and store modify the code to work using ALL Guidelines For each Calculation: ; Fib2 = Fib1 + Fib2 ; Fib1 = previous Fib2 ; R0 used for PUTS messages ; R1 contains current Fib1 value ; R2 contains current Fib2 value ; R6 is loop counter for main loop ; R7 is not used by this program.
