Note:
1.
Future devices may not support the described “Legacy Lock/Unlock” function. Thus bit 3 would have a value of “0.”
2.
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
4
following bytes are factory pre-programmed and user-programmable.
bits 0-7 = Lock/bytes JEDEC-plane physical low address
bits 8-15 = Lock/bytes JEDEC-plane physical high address
bits 16-23 = “n” such that 2n = factory pre-programmed bytes
bits 24-31 = “n” such that 2n = user-programmable bytes
Note:
1.
The variable P is a pointer which is defined at CFI offset 15h.
