5. Operation
This section explains operation of the low-voltage detection (external low-voltage detection).
The external low-voltage detection monitors the external voltage and generates an initialization reset or
interrupt if the external voltage drops below the configured value.
Those values of this register cannot be guaranteed if a low-voltage is detected and a settings initialization
reset occurs. After the low-voltage reset is released, the reset sequence will be executed without the
oscillation stabilization wait time, and then the program is restarted from the address specified by the reset
vector.
