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 SAMHA1

application code. For further information on how to configure and use the GPIO monitoring features, see 

Atmel Data Visualizer

 and the 

EDBG User Guide
