Interface
The bus interface has the following interface types.
Normal bus interface
DRAM interface
These interfaces can only be used in predetermined areas. The following table shows each chip selection area
and the usable interface functions.Which interface is to be used is selected in the Area Mode Register (AMD) .
If no selection is made, it defaults to the normal bus interface.
