6.4.2.1 Wake-Up Controller (WUC)
The WUC receives output signals from the WUC subscriber in the AON event fabric where power-on sequences can be triggered by configured input events from JTAG, AUX, or the MCU. JTAG has one wake-up event going to the WUC, while the AUX domain has three programmable input events and the MCU domain has four programmable input events. These specific input events are ORed together to form a single input to the WUC, one from the MCU and one from the AUX. Figure 6-5 shows this configuration. The inputs can be configured in the two selection registers, AON_EVENT:AUXWUSEL and AON_EVENT:MCUWUSEL. Any of the events listed in Table 6-5 can be chosen as input by selecting the appropriate event ID. By default, these IDs are set to 63 (NULL, no event), where the lines always stay logic low.
