Remark: This chapter applies to parts LPC1850/30/30/10 Rev ‘A’ only.
Remark: The event router controls the wake-up process and various event inputs to the
NVIC.
The available event router sources vary for different parts.
Table 15.
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:

The event router is connected to interrupt #42 in the NVIC (see
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,
