PRODUCTION DATA.
There are two on-chip Vector Interrupt Manager (VIM) modules. The VIM module provides hardware assistance for prioritizing and controlling the many interrupt sources present on a 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).
