I/O
Debug Port Serial Data Input or JTAG Port
Serial Data Input. Used on the MPC8xxFADS
as a debug port serial data driven by the debug
port controller. If the ADI bundle is not
connected to the MPC8xxFADS, this signal
can be driven by the external debug / JTAG
port controller.

Debug Port Serial Clock input or JTAG Port
Serial Clock input. Used on the MPC8xxFADS
as a debug port serial clock driven by the
debug port controller. If the ADI bundle is not
connected to the MPC8xxFADS, this signal
can be driven by the external debug / JTAG
port controller.
