Voltage monitor The development board provides a power supply voltage monitor and reset generator. When the +3.3V regulated supply voltage drops below 2.93V, the reset signal — RESET# — is asserted for a minimum of 140 msec. This signal is connected to the Digi Connect Wi-Wave edge connector (pin 22), as well as to the debug breakout header for monitoring.

Alternative methods to trigger

RESET#

In addition to supply voltage monitoring, reset logic can be triggered in two other ways. The RESET# signal is asserted when you do one of these actions:

Manually push SW1, a pushbutton reset switch on the development board

Pull low pin 15 on the JTAG breakout header, P20.
