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