4. (25 points) Design and write an MSP430 assembly language subroutine i2a (char*a, int myl) that converts a 16-bit BCD encoded integer, myl, into a character array with elements corresponding to the decimal representation of the integer. For example, an integer my9.746 (03246 in memory) is converted into an array with 4 elements as follows: [0]6',a[1-4, a 2j-17.3]/9. The main program that calls the subroutine is shown below.
