Four GPIO lines are connected to the Embedded Debugger. The EDBG can monitor these lines and time
stamp pin value changes. This makes it possible to accurately time stamp events in the SAM HA1
application code. For further information on how to configure and use the GPIO monitoring features, see
Atmel Data Visualizer
and the
EDBG User Guide
.
