[Note 1]

: When reset (whether in address/data separate mode or address/data multiplex mode)

: If block 1 in the external memory space is not used as a DRAM space, CS1 is selected; if block 1 is used

as a DRAM space, RAS1 is selected.

: If block 2 in the external memory space is not used as a DRAM space, CS2 is selected; if block 2 is used

as a DRAM space, RAS2 is selected.

Note: For details on the external memory space settings, refer to section 8.6, "Description of Registers."

[Note 2]

When the bus authority is granted, A23, CS3, CS2, RAS2, CS1, RAS1, and CS0 go to high impedance.
