The Event Router is a unique block that is available in some of the LPC2000 and LPC3000 devices. The main purpose of the event router is to use events to wake up the chip from idle mode via the CGU. To clarify, events in this context mean external and internal interrupts. As shown in this image, the Event Router interacts with the Vectored Interrupt Controller (VIC) in two ways: as a source of interrupt to the VIC (shown by the red line) or used as one of the sources to wake up the CGU (shown by the brown line).
