Legend： L = Logic Low = V_IL, H = Logic High = V_IH, V_ID = 8.5-11.5V, X = Don’t Care, SA = Sector Address, A_IN = Address In,
D_IN = Data In, D_OUT = Data Out
Notes：
1. Addresses are A19:A0 in word mode (#BYTE = V_IH), A19:A-1 in byte mode (#BYTE = V_IL).
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See
the” Sector Protection and Unprotect ion” section.Auto-select Codes (High Voltage Method)
