Processors’ Signal Interface Summary Table
Pin Description Tables
This section identifies all the signal pins by symbol name, type and description. Names
should follow the following convention, all capital letters with a trailing “_N” indicate a
signal is asserted when driven to a logic low (digital 0). The description includes the full
name of the pin along with a functional description. This section does not specify the
number of power and ground pins required, but does include the number of different
types of power pins required.
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.
