Preliminary
Part 5 Interrupt Controller (ITCN)
5.1 Introduction
The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to
signal 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
For further information, see
Table 4-2
, Interrupt Vector Table Contents.
5.3 Functional Description
The Interrupt Controller is a slave on the IPBus. It contains registers that allow each of the 46 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 45 is the lowest.
5.3.1
Once the INTC has determined that an interrupt is to be serviced and which interrupt has the highest
priority, an interrupt vector address is generated. Normal interrupt handling concatenates the Vector Base
Address (VBA) and the vector number to determine the vector address, generating an offset into the vector
table for each interrupt.
