AM275x contains two ESM modules to consolidate the error interrupts in SoC. One is in the MAIN domain and one is in the WKUP domain. ESM Connections shows how error interrupts are connected to these two ESM. .
The error interrupts from the WKUP_R5FSS domain are routed to both MAIN_ESM and WKUP_ESM. Users can configure ESM to cause ESM generating interrupt output from the interrupt inputs. The interrupt outputs of the MAIN_ESM are routed as interrupt inputs to the WKUP_ESM. The interrupt outputs of the WKUP_ESM are routed as the interrupt inputs to the MAIN_ESM. This means that user can configure the device to use one ESM to monitor the error interrupts for the whole device.
