4.5.3 Interrupts with Vector Table
Interrupt Manager with Interrupt Vector Table (IVT)
4.5.3.1 Introduction
The Interrupt Manager handles and prioritizes the interrupt requests from the different peripheral modules. It also provides APIs for users to control how global, peripheral, and external interrupts will be serviced. This Interrupt Manager module features a Interrupt Vector Table (IVT) which assigns a unique vector address for each interrupt source.
