/// !Purpose
/// 
/// Methods and definitions for configuring interrupts using the Advanced
/// Interrupt Controller (AIC).
/// 
/// !Usage
///
/// -# Configure an interrupt source using AIC_ConfigureIT
/// -# Enable or disable interrupt generation of a particular source with
///    AIC_EnableIT and AIC_DisableIT.
///
/// \note Most of the time, peripheral interrupts must be also configured
/// inside the peripheral itself.
