COMMAND SET (90/00h)
Notes:
x16
1. Key: A = Address and D = Data; X = "Don’t Care;" BAd = any address in the block; PWDn
= password bytes 0 to 7; PWAn = password address, n = 0 to 7; Gray = not applicable. All
values in the table are hexadecimal.
2. DQ[15:8] are "Don’t Care" during UNLOCK and COMMAND cycles. A[MAX:16] are
"Don’t Care" during UNLOCK and COMMAND cycles, unless an address is required.
3. The 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 and to
any other block are allowed. Also, when an ENTER COMMAND SET command is issued,
an EXIT PROTECTION COMMAND SET command must be issued to return the device to
READ mode.
4. READ REGISTER/PASSWORD commands have no command code; CE# and OE# are driven
LOW and data is read according to a specified address.
5. Data = Lock register content.
6. All address cycles shown for this command are READ cycles.
7. Only one portion of the password can be programmed or read by each PROGRAM PASS-
WORD command.
8. Each portion of the password can be entered or read in any order as long as the entire
64-bit password is entered or read.
