1.
Refer to
for signal descriptions.
2.
In processor systems where no debug port is implemented on the system board, these
signals are used to support a debug port interposer. In systems with the debug port
implemented on the system board, these signals are no connects.

3.
The value of these signals during the active-to-inactive edge of RESET# defines the
processor configuration options. See
processor configuration options. See
