SD : Sector protection verify data. Output 01h at protected sector addresses and output 00h at unprotected sector addresses. *1: This command is valid while Fast Mode. *2: This command is valid while RESET= VID. *3: This data “00h” is also acceptable. MBM29LV400TC/400BC Sector Protection Verify Autoselect Codes *1: A-1 is for Byte mode. In byte mode, DQ8 to DQ14 become “High-Z” and DQ15 becomes the lower address A-1. *2: Outputs 01h at protected sector addresses and outputs 00h at unprotected sector addresses. Extended Autoselect Code Table (B): Byte mode (W): Word mode HI-Z : High-Z * : At Byte mode, DQ8 to DQ14 are High-Z and DQ15 is A-1, the lowest address.
