How to bubble sort in assembly language for two arrays (for MSP430)?

;1. SORT1 sets R4/R5/R6 parameters used to SORT subroutine to sort ARY1

;2. R4-starting address of array

;3. R5-length of array

;4. R6-holds address where sorted array will be stored

;5. SORT2 will sort array ARY2 in the same way

;6. Sort Arrays in increasing order from lowest to highest value.

For ex: ARY1: (17,75,-67,23,36,-7,44,8,-74,18),

ARY2: (54,-4,-23,-19,-72,-7,36,62,0,39)
