Number of Protection register fields in JEDEC ID space.
“00h,” indicates that 256 protection bytes are available
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.
Reserved for future use
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
bits 24–31 = “n” such that 2
