The reset push button does not reset the standalone debug agent once the
debug agent is connected to a personal computer (PC). After communica-
tion between the debug agent and PC is initialized, pushing a reset button
does not reset the USB chip on the debug agent. The only way to reset the
USB chip on the debug agent is to power down the EZ-Board.
Programmable Flag Push Buttons (SW12–13)
Two momentary push buttons (
eral-purpose user input. The buttons connect to the
pins of the processor. The push buttons are active high and, when pressed,
send a high ( ) to the processor. The GPIO enable switch (
