Ann,

The table you posted in the other thread shows which signals are monitored by these two outputs. If you look at the figure 6.4.5.1 in the datasheet you can see how these outputs wait for the signals in this table before going high.

Ann,

These signals will only go low when one of these qualifying signals goes low.

Thank you,

Nick
