1 Bus operations defined in "Mode definitions," on page 3.
2 Reading from and programming to non-erasing sectors allowed in Erase Suspend mode.
3 Address bits A11-A18 = X = Don’t Care for all address commands except where Program Address and Sector Address are required.
4 Data bits DQ15-DQ8 are don’t care for unlock and command cycles.
5 The Unlock Bypass command must be initiated before the Unlock Bypass Program command.
6 The Unlock Bypass Reset command returns the device to reading array data when it is in the unlock bypass mode.
