/// !Purpose
/// 
/// This module provides definitions and functions for using the DBGU.
///
/// !Usage

/// -# Enable the DBGU pins (see pio.h).
/// -# Configure the DBGU using DBGU_Configure.
///
/// \note Unless specified, all the functions defined here operate synchronously;
/// i.e. they all wait the data is sent/received before returning.
