A signal called active high specifies that the interface is active when driven to a logic 1
and inactive when driven to a logic 0.
A signal called active low specifies that the interface is active when driven to a logic 0
and inactive when driven to a logic 1.
The following information attempts to explain how to interpret the tables. There are
five vertical columns:

logic 0, the part will exhibit this behavior.
The intent of this is to allow the interface to be brought out of reset to a state,
which will not cause any protocol violations or any damage to the parts prior to
being enabled via software. This state will occur when both Power on Reset and
Reset are driven to a logic 1.
the part is capable of behaving with appropriate software written. This state will
occur when both Power on Reset and Reset are driven to a logic 1.
