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 2
