A software test for testing the basic functionality as well as failure modes such as continuous interrupts, no interrupts, and crossover interrupts can be implemented. Such testing can be based on generating the interrupts from the peripherals (using either software force capability, for example, ECAP_REGS.ECFRC.CTROVF or creating the interrupt scenario functionally, for example, creating a counter overflow condition in ECAP) and ensuring that the interrupt is serviced and serviced in proper order. Error response, diagnostic testability, and any necessary software requirements are defined by the software implemented by the system integrator.
