A software test for detecting basic functionality as well as errors for reset sources and reset logic can be implemented. Each of the reset sources (including peripheral resets, DEV_CFG_REGS.SOFTPRESx) except POR can be generated internally and the basic reset functionality can be checked by ensuring the correct setting of reset cause register and making sure only the intended logic is reset. Additionally, the SIMRESET configuration for SYSRS or XRS assertion through software write may be used for this test.

In order to confirm if individual peripherals have received the reset correctly, software can run a peripheral specific test of functionality and confirm the expected state of the peripheral after reset. Depending on the complexity of the peripheral this software test of functionality can include testing of complex features of the peripheral including error tests necessary to confirm correct propagation of reset. For peripheral specific software test of function including error tests, see the device-specific safety mechanism listed for the peripheral.
