The ESM module generates three output interrupts to the device interrupt controllers:
The error interrupt outputs are provided so that a processor in the device can be signaled to intervene when an error event occurs. Each error event input can be enabled, via software, to cause an error interrupt to occur (via the ESM_INTR_EN_SET_j register). Additionally, each error event input can be programmed to influence either the low priority (default) interrupt or the high priority interrupt (via the ESM_INT_PRIO_j). The low priority interrupt is intended for events that are of interest, but do not require immediate intervention. For example, an indication that there was a single bit error that was corrected may signal a low priority interrupt, so that information can be collected for statistical purposes. A high priority interrupt is intended for events that need immediate attention. For example, an indication that there was an uncorrected two-bit error may be signaled as a high priority interrupt.
