When "0", the read from DRAM mode is set. (default) When "1", the write to DRAM mode is set. DRADR: This bit sets the address control method for access from the microcomputer to the DRAM. When "0", relative address control is set. (default) When "1", absolute address control is set. DRD15 to DRD0: These bits set the data to be written to the DRAM for access from the microcomputer to the DRAM. $A9F commands (preset: $A9F00000) Data 1 D3 1 D2 0 D1 0 D0 1 D3 1 D2 1 D1 1 D0 1 D3 DADR19 D2 DADR18 D1 DADR17 D0 DADR16 D3 DADR15 D2 DADR14 D1 DADR13 D0 DADR12 A9F (DRAM I/F) Data 2 Data 3 Data 4 Command D3 DADR11 D2 DADR10 D1 DADR9 D0 DADR8 D3 DADR7 D2 DADR6 D1 DADR5 D0 DADR4 D3 DADR3 D2 DADR2 D1 DADR1 D0 DADR0 Data 5 Data 6 Data 7 DADR19 to DADR0: These bits set the DRAM address for access from the microcomputer to the DRAM. |
