First, I see the following IFC architecture FTF presentaton, is there anything more recent from FTF or documented that gives a deep dive or detailed description of the IFC specific to the LS1043ARDB?
Second, why is an external latch required for the ADV NOR flash but not for the non ADV NOR flash?
Third, is the LS1043ARDB eval board using ADV or NON-ADV flash and does it have a latch?
"External latch is not needed for ADV NOR flash. For non ADV NOR flash, address latch is needed."
