Detailed explanation-1: -This action is called a “Brown Out Reset ‘’ or BOR. A similar feature is called Low Voltage Detect (LVD) which is more complex and adds detection of multiple voltage levels and can produce an interrupt before a reset is triggered. BOR is often enabled by a bit in a control register.
Detailed explanation-2: -Brownout is used to increase the robustness of an application to computing capacity shortage. If too many users are simultaneously accessing an application hosted online, the underlying computing infrastructure may become overloaded, rendering the application unresponsive.
Detailed explanation-3: -Intentional brownouts are used for load reduction in an emergency, or to prevent a total grid power outage due to high demand. The term brownout comes from the dimming of incandescent lighting when voltage reduces.
Detailed explanation-4: -The results of a power on reset and a brown-out reset are exactly the same. The Power On Reset Flag in the RSTSRC register will be set in both cases. As a result, it is not possible to differentiate between a power on reset and a brown-out reset.
