Part 5 Interrupt Controller (ITCN)
5.1 Introduction
The Interrupt Controller (ITCN) module arbitrates between various interrupt requests (IRQs), signals to
the 56800E core when an interrupt of sufficient priority exists, and to what address to jump in order to
service this interrupt.
5.2 Features
The ITCN module design includes these distinctive features:

5.3 Functional Description
The Interrupt Controller is a slave on the IPBus. It contains registers that allow each of the 64 interrupt
sources to be set to one of four priority levels (excluding certain interrupts that are of fixed priority). Next,
all of the interrupt requests of a given level are priority encoded to determine the lowest numerical value
of the active interrupt requests for that level. Within a given priority level, number 0 is the highest priority
and number 63 is the lowest.
