Registers
The device feature two registers:
Lock register
The lock register is a 16-bit one-time programmable register. The bits in the lock register are
summarized in
See
to read and program the lock register.
Password protection mode lock bit (DQ2)
The password protection mode lock bit, DQ2, is one-time programmable. Programming
(setting to ‘0’) this bit permanently places the device in password protection mode.
Any attempt to program the password protection mode lock bit when the non-volatile
protection mode bit is programmed causes the operation to abort and the device to return to
read mode.
Non-volatile protection mode lock bit (DQ1)
The non-volatile protection mode lock bit, DQ1, is one-time programmable. Programming
(setting to ‘0’) this bit permanently places the device in non-volatile protection mode.
When shipped from the factory, all parts default to operate in non-volatile protection mode.
The memory blocks can be either unprotected (NVPBs set to ‘1’) or protected (NVPBs set to
‘0’), according to the ordering option that has been chosen.
Any attempt to program the non-volatile protection mode lock bit when the password
protection mode bit is programmed causes the operation to abort and the device to return to
read mode.
Extended block protection bit (DQ0)
If the device has not been shipped with the extended memory block factory locked, the
block can be protected by setting the extended memory block protection bit, DQ0, to ‘0’.
However, this bit is one-time programmable and once protected the extended memory block
cannot be unprotected.
The extended memory block protection status can be read in auto select mode either by
applying V
