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.

bit 0 to 7 Lock/bytes JEDEC-plane physical low address

bit 8 to 15Lock/bytes JEDEC-plane physical high address

bit 16 to 23 "n" such that 2n = factory pre-programmed bytes

bit 24 to 31 "n" such that 2n = user programmable bytes
