42.2.1 How to read this chapter
42.2.2 Basic configuration
42.2.3 General description
Remark: The event router controls various event inputs to the NVIC and the wake-up
process.
The available event router sources vary for different parts.
Table 901. Event router clocking and power control
The event router is used to process wake-up events such as certain interrupts and
external or internal inputs for wake-up from any of the low power modes (Sleep,
Deep-sleep, Power-down, and Deep power-down modes). The event router has multiple
event inputs from various peripherals. When the proper edge detection is set in the EDGE
configuration register, the event router can wake up the part or can raise an interrupt in the
NVIC.
Each event input to the event router can be configured to trigger an output signal on rising
or falling edges or on HIGH or LOW levels. The event router combines all events to an
output signal which is used as follows:
Remark: The ATIMER, RTC, BOD, WDT, CAN and QEI events are routed through the
event router and have no direct connection to the NVIC. When proper edge detection in
the Event router is set for the peripheral events, the event router can generate an interrupt
in the NVIC.

Ethernet: available on LPC1850/30.
USB0: available on LPC1850/30/20.
USB1: available on LPC1850/30.
Create an interrupt if the event router interrupt is enabled in the NVIC.
Send a wake-up signal to the power management unit to wake up from Deep-sleep,
Power-down, and Deep power-down modes.
Send a wake-up signal to CCU1 and CCU2 for waking up from Sleep mode (see
Section
14.5.3).
