Notes:
1. Dual Output data
DQ₀ = (D6, D4, D2, D0)
DQ₁ = (D7, D5, D3, D1)
2. Dual Input Address
DQ₀ = A22, A20, A18, A16, A14, A12, A10, A8 ; A6, A4, A2, A0, dummy 6, dummy 4, dummy 2, dummy 0
DQ₁ = A23, A21, A19, A17, A15, A13, A11, A9 ; A7, A5, A3, A1, dummy 7, dummy 5, dummy 3, dummy 1
3. Quad Data
DQ₀ = (D4, D0, …… )
DQ₁ = (D5, D1, …… )
DQ₂ = (D6, D2, …... )
DQ₃ = (D7, D3, …... )
4. Quad Input Address
DQ₀ = A20, A16, A12, A8, A4, A0, dummy 4, dummy 0
DQ₁ = A21, A17, A13, A9, A5, A1, dummy 5, dummy 1
DQ₂ = A22, A18, A14, A10, A6, A2, dummy 6, dummy 2
DQ₃ = A23, A19, A15, A11, A7, A3, dummy 7, dummy 3
5. Quad I/O Fast Read Data
DQ₀ = ( dummy 12, dummy 8, dummy 4, dummy 0, D4, D0 )
DQ₁ = ( dummy 13, dummy 9, dummy 5, dummy 1, D5, D1 )
DQ₂ = ( dummy 14, dummy 10, dummy 6, dummy 2, D6, D2 )
DQ₃ = ( dummy 15, dummy 11, dummy 7, dummy 3, D7, D3 )
6. Set burst and Wrap Length
Table 5. Burst length configuration table
Data to setup Burst length
Burst wrap (A[7:A0]) address range
00h
8 Bytes ( default) 00-07H, 08-0FH, 10-17H, 18-1FH...
01h
16 Bytes
00-0FH, 10-1FH, 20-2FH, 30-3FH...
02h
32 Bytes
00-1FH, 20-3FH, 40-5FH, 60-7FH...
03h
64 Bytes
00-3FH, 40-7FH, 80-BFH, C0-FFH
04h
128 Bytes
00-7FH, 80-FFH
05h
256 Bytes
00-FFH
If input data is not between 00h~05h or user does not Set Burst, the Burst length will be 8 Bytes in
default.
7. Two dummy cycles (4 clocks) are necessary for Read Burst with Wrap mode.
