Figure 9-1.
The Event Routing Network can directly connect together ADCs, DACs, Analog Comparators
(ACx), I/O ports (PORTx), the Real-time Counter (RTC), Timer/Counters (T/C) and the IR Com-
munication Module (IRCOM). Events can also be generated from software (CPU).
All events from all peripherals are always routed into the Event Routing Network. This consist of
eight multiplexers where each can be configured in software to select which event to be routed
into that event channel. All eight event channels are connected to the peripherals that can use
events, and each of these peripherals can be configured to use events from one or more event
channels to automatically trigger a software selectable action.
