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:
Programmable priority levels for each IRQ
Two programmable Fast Interrupts
Notification to SIM module to restart clocks out of Wait and Stop modes
Ability to drive initial address on the address bus after reset
