Debug
A debugger can control all OCD features by writing OCD registers over the SAB interface. Many
of these do not depend on output on the AUX port, allowing an aWire- or JTAG-based debugger
to be used.
A JTAG-based debugger should connect to the device through a standard 10-pin IDC connector
as described in the AVR32UC Technical Reference Manual.
An aWire-based debugger should connect to the device through the RESET_N pin.
