Number of Protection register fields in JEDEC ID space.
Protection Field 1: Protection Description
Protection Field 2: Protection Description
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 2
“00h,” indicates that 256 protection fields are available
This field describes user-available One Time Programmable
(OTP) Protection register bytes. Some are pre-programmed
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.
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
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.
