Ad address, Dat data, BAd any address in the block, RD read data, PWDn password word 0 to 3, PWAn password address (n = 0 to 3), X don’t care. All values in
the table are in hexadecimal.
Grey cells represent read cycles. The other cells are write cycles.
DQ15 to DQ8 are ‘don’t care’ during unlock and command cycles. A22 to A16 are ‘don’t care’ during unlock and command cycles unless an address is required.
An Enter command sequence must be issued prior to any operation. It disables read and write operations from and to block 0. Read and write operations from any
other block are allowed.
DATA = lock register content.
Only one portion of password can be programmed or read by each Password Program command.
The password portion can be entered or read in any order as long as the entire 64-bit password is entered or read.
Protected and unprotected states correspond to 00 and 01, respectively.
The Clear all NVPBs command programs all NVPBs before erasure in order to prevent the over-erasure of previously cleared non-volatile modify protection bits.
