I am designing a system using LS1021A, the design checklist for LS1021A has two columns i.e, 'Used' and 'Not used' for checking each pin design. It is not clear to me that the Used and Not used columns are based on interface use or pin use basis.
Example,In the Design Checklist IFC_CS[0:6]_B is to be pulled up in Used case and is to be left unconnected in Not used case. So if the IFC interface is used I need to pull up all pins and if pins are used then I need to pull up respective used pins only.
Would be glad if anyone could clarify the case.
