In this use case, the MAIN_ESM is used to consolidate all the error interrupts in the MAIN domain and the WKUP_R5FSS domain as MAIN_ESM’s interrupt outputs, which are routed as interrupt inputs to the WKUP_ESM.
In this use case, the MAIN_ESM should be configured to disable the interrupt inputs coming from the WKUP_ESM interrupts. If those interrupt inputs are not disabled by the MAIN_ESM, the dependence loop will be formed as following:
In addition, since WKUP_R5FSS error events are already routed to the MAIN_ESM, so the input events in the WKUP_ESM connecting to those error events from the WKUP_R5FSS domain shall be disabled, otherwise those events can trigger the interrupt in both the MAIN_ESM as well as the WKUP_ESM
