An external reset is generated by a low level on the RESET pin. Reset pulses longer
than 50 ns will generate a reset even if the clock is not running. Shorter pulses are not
guaranteed to generate a reset. When the applied signal reaches the Reset Threshold
Voltage (V
) on its positive edge, the delay timer starts the MCU after the Time-out
RST
period t
has expired.
