6.14 Vectored Interrupt Manager
The vectored interrupt manager (VIM) provides hardware assistance for prioritizing and controlling the
many interrupt sources present on this device. Interrupts are caused by events outside of the normal flow
of program execution. Normally, these events require a timely response from the CPU; therefore, when an
interrupt occurs, the CPU switches execution from the normal program flow to an interrupt service routine
(ISR).
6.14.1 VIM Features
The VIM module has the following features:
• Supports 128 interrupt channels.
– Provides programmable priority and enable for interrupt request lines.
• Provides a direct hardware dispatch mechanism for fastest IRQ dispatch.
• Provides two software dispatch mechanisms when the CPU VIC port is not used.
– Index interrupt
– Register vectored interrupt
• Parity protected vector interrupt table against soft errors.
