Protection Register Lock
64 bits: unique device number
128 bits: User Programmable OTP
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.
