; File Notes:
; 1. This file contains the "_main" routine. The run-time C start-up library
;    will bring code execution to the label "_main" after initializing
;    data RAM.
; 2. All peripheral initialization routines are called in this file.
;    To understand what functions the peripherals will perform in this demo
;    please see headers and comments in the associated peripheral init_ files.
