Note The Digi Connect ME and Digi Connect Wi-ME modules use a supervisor
circuit with a 2.88 reset threshold and an internal 5k pull-up resistor. When
VCC falls to the threshold voltage, a reset pulse is issued, holding the
output in active state. When power rises above 2.88V, the reset remains for
approximately 250 ms to allow the system clock and other circuits to
stabilize.
Note The Digi Connect EM and Digi Connect Wi-EM modules use a supervisory
circuit with a 2.93V reset threshold. 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.
