- /// 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.
