LPC2364/65/66/67/68

Single-chip 16-bit/32-bit microcontrollers

7.5 Interrupt controller

The ARM processor core has two interrupt inputs called Interrupt Request (IRQ) and Fast

Interrupt Request (FIQ). The VIC takes 32 interrupt request inputs which can be

programmed as FIQ or vectored IRQ types. The programmable assignment scheme

means that priorities of interrupts from the various peripherals can be dynamically

assigned and adjusted.
