Vectored Interrupt Controller
EP93xx User’s Guide

Any 16 of the 32 interrupts (per VIC) can be designated as ‘vectored’ by programming the
Vector address registers, ‘VICxVectAddr0’ on page 6-15 and the Vector Control registers,
‘VICxVectCntl0,’ on page 6-17.
An interrupt is designated as either IRQ or FIQ by programming the VICxIntSelect register.
The IRQ and FIQ request logic has an asynchronous path. This allows interrupts to be
asserted when the clock is disabled.
Software can generate a specific interrupt by writing a ‘1’ to the associated bit in the
VICxSoftInt register.
