Question

write a program that coutns the number of elements in an array that are even number, the array has 11 elements, each 16 bit and is stored in memory location starting from $800 (higher byte at $800, lower byte at $801). your code should start from $C000. include algorithm and flowchart with your code, (the language shoud be assembly language so it could be used on motorola 68hc11

Explanation / Answer

Solution :

Step 1:memory is loaded with the location at $800 into accumulator A.
Step 2:The contents of the memory location is at $801 into accumulator A.
Step 3: the contents of the memory location is added at $802 into accumulator A.
Step 4: the contents of accumulator A stored at memory location $900.

These steps can be translated into the as12 assembly program as follows:
Start of the program
org $1000 ;
ldaa $800 ; the contents is placed at memory location $800 into A
adda $801 ;
adda $802 ;
staa $900 ;
end
