The embedded modules use a supervisory circuit with a 2.93V reset threshold.
Note
When VCC falls to the threshold voltage, a reset pulse is issued, holding the
output in active state. When power rises above 2.93V, the reset remains for
approximately 200 ms to allow the system clock and other circuits to stabilize.
