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.

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
