Read-Lock
‘1’
Bus Read operations in this Block always return 00h.
‘0’
Bus read operations in this Block return the Memory Array contents. (Default
value).
1
Lock-Down
‘1’
Changes to the Read-Lock bit and the Write-Lock bit cannot be performed. Once a
‘1’ is written to the Lock-Down bit it cannot be cleared to ‘0’; the bit is always reset
to ‘0’ following a Reset (using RP or INIT) or after power-up.
‘0’
Read-Lock and Write-Lock can be changed by writing new values to them. (Default
value).
0
Write-Lock
‘1’
Program and Block Erase operations in this Block will set an error in the Status
Register. The memory contents will not be changed. (Default value).
‘0’
Program and Block Erase operations in this Block are executed and will modify the
Block contents.
