PREHEAT oven to 350°F. Line 13x9-inch baking pan with foil, with ends of foil extending over sides of pan. Mix graham crumbs, 1/2 cup of the pecans, the granulated sugar and butter; press firmly onto bottom of prepared pan. Bake 10 min.

Add eggs, one at a time, mixing on low speed after each addition just until blended. Place 36 of the caramels in microwaveable bowl. Add 1 Tbsp. of the water. Microwave on HIGH 1 min. or until caramels are completely melted when stirred. Add to cream cheese batter; stir until well blended. Pour over crust.

BAKE 40 min. or until center is almost set. Sprinkle with remaining 1/2 cup pecans. Cool completely. Refrigerate at least 4 hours.

PLACE remaining caramels in microwaveable bowl. Add remaining 1 Tbsp. water. Microwave on HIGH 1 min. or until caramels are completely melted when stirred. Drizzle over cheesecake; let stand until firm. Use foil handles to remove dessert from pan before cutting into bars to serve. Store leftovers in refrigerator.
