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.
bit 0 to 7 Lock/bytes JEDEC-plane physical low address
bit 8 to 15Lock/bytes JEDEC-plane physical high address
bit 16 to 23 "n" such that 2n = factory pre-programmed bytes
bit 24 to 31 "n" such that 2n = user programmable bytes
