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.
