Protection Register Lock
64 bits: unique device number
128 bits: user programmable OTP
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.
