HWBIST diagnostic has capability helps to inject faults. HWBIST module expects the self-test to be completed within a certain time frame. If the test is not completed within this time frame, the test is stopped immediately, CPU is reset and NMI (and hence ERRORSTS) is issued to recover from the indeterminate state. This feature is enabled by default once the HWBIST module enters into self-test mode and cannot be disabled by software. After coming out from reset, CPU can read the HWBIST status registers to understand the reset cause and take the required action.
