Future devices may not support the described “Legacy Lock/Unlock” function. Thus bit 3 would have a value of “0.”
Setting this bit, will lead to the extension of the CFI table.

Protection Field 1: Protection Description
This field describes user-available One Time Programmable (OTP)
protection register bytes. Some are pre-programmed with device-
unique serial numbers. Others are user-programmable. Bits 0-15 point
to the protection register lock byte, the section’s first byte. The
following bytes are factory pre-programmed and user-programmable.
