On this pin, the QSE periodically puts out an information
packet which indicates if all multicast buffers are empty or
not.
There is a software configurable mode in which the
STAT_OUT pin ceases to be an output pin, and instead
turns into an input pin that performs “/No Data In”
functionality. (The complementary funcion of “/No Data
Out” is performed by the CTRL_IN pin; see above). That
is, whenever STAT_OUT is pulled low, the QSE will not
accept any incoming cell.
After Reset, the above mode is on by default; that is, the
STAT_OUT pin is configured as “/No Data In”.
