Note: The system should generate the following address patterns: • Byte mode when V_IL is inputted to CIOF, and addresses
Word Mode: 555H or 2AAH to addresses A10~A0
are A22~A0
Byte Mode: AAAH or 555H to addresses A10~A0, A12F
• Write mode when V_IH is inputted to CIOF, and addresses
DQ8~DQ15 are ignored in Word mode.
are A21~A0
• Valid addresses are A10~A0 when a command is entered.
(1) RA: Read Address
(6) PA: Program Address
(2) RD: Read Data
(7) PD: Program Data
(3) BK: Bank Address = A21~A15
(8) BA: Block Address = A21~A12
(4) IA: Bank Address and ID Read Address (A6, A1, A0) _{(9) BPA: Block Address and ID Read Address (A6, A1, A0)}
Bank Address = A21~A15
Manufacturer Code = (0, 0, 0)
Device Code = (0, 0, 1)
Block Address = A21~A12
ID Read Address = (0, 1, 0)
(5) ID: ID Data
(10) BPD: Verify Data
0098H - Manufacturer Code
(11) CA: CFI Address
0093H - Device Code (TH50VSF3680AASB) ^{(12) CD: CFI Data}
0095H - Device Code (TH50VSF3681AASB) (13) F0H: 00H is valid too
0001H - Protected Block
