Debug Port Signals
In order to fully support debugging of customer platforms, it is
mandatory
that customer designs allow access to the
signals listed in
Table 3-15, “RS690M Debug Port Signals,”
and
Table 3-16, “RS690T Debug Port Signals”
below.
For debug ports on the side-port memory signals of the RS690T, an acceptable implementation of an access point will be
an opening in the solder mask for the required signal traces. Adding stubs to side-port memory signals for the purpose is
not recommended. Other signals in the table should be brought out to test points on the motherboard.
