Clear Lock bit command
The Clear Lock bit command individually clears (sets to ‘0’) the Lock bit for a given block or
group of blocks.
If the Non-Volatile Lock bit for the same block or group of blocks is set, the block or group of
blocks remains locked (see
Verify Lock bit command
The status of a Lock bit for a given block can be read by issuing a Verify Lock bit command
along with the block address.
Set Lock-Down bit command
This command is used to set the Lock-Down bit to ‘1’ thus protecting the Non-Volatile Modify
Protection bits from program and erase.
There is no Unprotect Lock-Down bit command.
Verify Lock-Down bit command
This command is used to read the status of the Lock-Down bit. The status is output on bit
DQ1. If DQ1 is ‘1’, all the Non-Volatile Modify Protection bits are protected from Program or
Erase Operations.
