4 Protection Field 1: Protection Description
(P+10)h
This field describes user-available One Time Programmable
(P+11)h
(OTP) Protection register bytes. Some are pre-programmed
(P+12)h
w ith device-unique serial numbers. Others are user
programmable. Bits 0–15 point to the Protection register Lock
byte, the section’s first byte. The follow ing bytes are factory
pre-programmed and user-programmable.

10 Protection Field 2: Protection Description
Bits 0–31 point to the Protection register physical Lock-w ord
address in the Jedec-plane.
Follow ing bytes are factory or user-programmable.
bits 32–39 = “n” such that n = factory pgm'd groups (low byte)
bits 40–47 = “n” such that n = factory pgm'd groups (high byte)
bits 48–55 = “n” \ 2n = factory programmable bytes/group
bits 56–63 = “n” such that n = user pgm'd groups (low byte)
bits 64–71 = “n” such that n = user pgm'd groups (high byte)
bits 72–79 = “n” such that 2ⁿ = user programmable bytes/group
