Description
(Optional flash features and commands)
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.
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
