Block Locking
60h
Lock Setup
This command prepares the CUI lock configuration. If the next command is not
Lock Block, Unlock Block, or Lock-Down, the CUI sets SR[5:4] to indicate
command sequence error.
01h
Lock Block
If the previous command was Lock Setup (60h), the CUI locks the addressed
block.
D0h
Unlock Block
If the previous command was Lock Setup (60h), the CUI latches the address and
unlocks the addressed block. If previously locked-down, the operation has no
effect.
2Fh
Lock-Down
If the previous command was Lock Setup (60h), the CUI latches the address and
locks-down the addressed block.
Protection
C0h
Protection
Program
Setup
This command prepares the CUI for a protection register program operation. The
second cycle latches address and data, and starts the WSM’s protection register
program or lock algorithm. Toggling CE# or OE# updates the flash Status
Register data. To read array data after programming, issue a Read Array
command.
Configuration
60h
Configuration
Setup
This command prepares the CUI for device configuration. If Set Configuration
Register is not the next command, the CUI sets SR[5:4] to indicate command
sequence error.
03h
Set
Configuration
Register
If the previous command was Configuration Setup (60h), the CUI latches the
address and writes the data from A[15:0] into the configuration register.
Subsequent read operations access array data.
Note:
Do not use unassigned commands. Intel reserves the right to redefine these codes for future functions.
