Lock Register
User can choose Secured Silicon Sector Protection Bit for security sector protection method via setting
the Lock Register bit, DQ0. Lock Register is a 16-bit one time programmable register. Once
programmed DQ0, will be locked in that mode permanently.
Once the Instruction Set Entry instruction sequence for the Lock Register Bits is issued, all sectors
read and write functions are disabled until Lock Register Exit sequence has been executed.
The memory sectors and extended memory sector protection is configured using the Lock Register.
