i need this code to work by
- Calculate 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
Fib2 the largest Fibonacci number calculates so far
; Fib1 the previous Fibonacci number
;
; 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. Used by Simulate for TRAP and Subroutines

ADD R6, R6, #5; Init Main Loop counter (loop 5 times)
;Print first 2 Fib values before starting
;----- Your Code Here -----;
ADD R1, R1, #0 ; R1 initialized to 0
ADD R2, R2, #1 ; R2 initialized to 1
;----- End Your Code Here -----;
;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
MainLoop
;----- Your Code Here -----;
AND R7, R7, #0 ; clear R7
ADD R7, R7, R2 ; copy value of R2 to R7
JSR calcNextFib ; call subroutine to calculate next fibonacci number
JSR printNum ; print the number
JSR printCommaSpace ; print comma and space
AND R2, R2, #0 ; clear R2
ADD R2, R2, R7 ; restore value of R2 from R7
ADD R6, R6, #-1 ; reduce loop counter
BRp MainLoop ; continue the loop if R6 is not yet 0
