How to create an array in assembly for 68hc11?

Question

I need to write a program that will execute from $100, allocate a 200-byte array at $800, and initialize that array with the values 200, 199, … 1.

I need to know how to create a loop that will decrement an array while decrementing the value to be stored in an array.

Any ideas or suggestions? I cannot find alot of example code for this processor.

ORG  $100

      LDAA #200
      STAA #$800
      DECA
      BNE  

Answer 1

Vreset              equ       $FFFE
RAM                 equ       $800
ROM                 equ       $100

ARRAY_SIZE          equ       200

                    org       RAM

array               rmb       ARRAY_SIZE

                    org       ROM

Start               ldx       #array
                    ldaa      #ARRAY_SIZE
Loop                staa      ,x
                    inx
                    deca
                    bne       Loop

                    bra       *

                    org       Vreset
                    dw        Start
