9.4.2 State Machine

The state machine processes the independent monitoring of the voltage domains. The state machine updates the source select signal on each rising clock edge using a round-robin scheme. The factory scan sources are listed in Table 9-3. If any of the scan sources trigger an OV or UV event, a device Reset will occur.
