This method does not require VID. Refer to the Autoselect Command Sequence on page 56 for more information. Legend L = Logic Low = VIL, H = Logic High = VIH, BA = Bank Address, SA = Sector Address, X = Don’t care. Note When Polling the Secured Silicon indicator bit the Bank Address (BA) should be set within the address range 004000h-03FFFFh. Legend L = Logic Low = VIL, H = Logic High = VIH, BA = Bank Address, SA = Sector Address, X = Don’t care. Note 1. When Polling the Secured Silicon indicator bit the A21 to A12 should be set within the address range 004000h-03FFFFh. 2. The autoselect codes may also be accessed in-system by using the command sequences Table 10.10 Autoselect Codes (High Voltage Method) Description CE# OE# WE# Amax to A12 A10 A9 A8 A7 A6 A5 to A4 A3 A2 A1 A0 DQ15 to DQ0 Manufacturer ID: Spansion products LL H BA X VI D X L L X LLLL 0001h Read Cycle 1 L LH BA X VI D XL L L LLL H 227Eh Read Cycle 2 L H H H L 2220h (PL127J) 2202h (PL064J) 220Ah (PL032J) Read Cycle 3 L H H H H 2200h (PL127J) 2201h (PL064J) 2201h (PL032J) Sector Protection Verification LL H SA X VI D XL L L L L H L 0001h (protected), 0000h (unprotected) Secured Silicon Indicator Bit (DQ7, DQ6) LL H BA (See Note) X VI D XX L X L L H H DQ7=1 (factory locked), DQ6=1 (factory and customer locked) Table 10.11 Autoselect Codes for PL129J Description CE1# CE2# OE# WE# A21 to A12 A10 A9 A8 A7 A6 A5 to A4 A3 A2 A1 A0 DQ15 to DQ0 Manufacturer ID: Spansion products LH LH X X VI D X L L X L L L L 0001h HL Read Cycle 1 LH LH X X VI D X LLL LLL H 227Eh HL Read Cycle 2 LH H H H L 2221h HL Read Cycle 3 LH H H H H 2200h HL Sector Protection Verification LH LH SA X VI D X LLL LL H L 0001h (protected), 0000h (unprotected) HL Secured Silicon Indicator Bit (DQ7, DQ6) LH LH X (Note 1) X VI D XX L X L L H H DQ7=1 (factory locked), DQ6=1 (factory and customer locked) HL |
