Write a MC68HC12 assembly language program to average ten 16-bit values that are stored starting at address $1100. Place the two-byte result at $1110. Use indexed addressing.
Using the FCB or FDB directives might be useful here.
FCB (Form Constant Byte) Example:
ORG $4000
FCB $02, $05;
(The above two lines will place constant byte $02 in address $4000, and constant byte $05 in address $4001)
FDB (Form Double Byte)
Example:
FDB $02, $05, $2445;
(The above two lines will place constant bytes as explained below:
$00 in address $4000, and $02 in address $4001,
$00 in address $4002, and $05 in address $4003
$24 in address $4004, and $45 in address $4005
