Issue this command sequence to return to Read State after detecting device is in a Write-to-Buffer-Abort state. IMPORTANT: the full command sequence is required if resetting out of ABORT. 14. The Exit command returns the device to reading the array. 15. The password portion can be entered or read in any order as long as the entire 64-bit password is entered or read. Addresses are 10h-13h if the SSR3 is being accessed. 16. For PWDx, only one portion of the password can be programmed per each A0 command. Portions of the password must be programmed in sequential order (PWD0 - PWD3). 17. All Lock Register bits are one-time programmable. The program state = 0 and the erase state = 1. Also, both the Persistent Protection Mode Lock Bit and the Password Protection Mode Lock Bit cannot be programmed at the same time or the Lock Register Bits Program operation halts and returns the device to Read State. Lock Register bits that are reserved for future use are undefined and may be 0’s or 1's. 18. If any of the Entry commands was issued, an Exit command must be issued to reset the device into Read State. 19. Protected State = 00h, Unprotected State = 01h. The sector address for DYB set, DYB clear, or PPB Program command may be any location within the sector - the lower order bits of the sector address are don't care. 20. See Section 5.4.7.2, Sector Erase on page 30 for description of Multi-Sector Erase.
