Protection Field 1: Protection Description
This field describes user-available One Time Programmable (OTP) Protection
register bytes.
• Some bytes are pre-programmed with flash device-unique serial
numbers.
• Other bytes are user programmable.
Bits 0-15 point to the Protection register Lock byte, the first byte in the
section. The following bytes are factory pre-programmed and userprogrammable.
• 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

read-page bytes. See offset 28h for device word width to
determine page-mode data output width. 00h indicates no
read page buffer.

bits 0–2 “n” such that 2 n+1 HEX value represents the
maximum number of continuous synchronous reads when
the device is configured for its maximum word width. A value
of 07h indicates that the device is capable of continuous
linear bursts that will output data until the internal burst
counter reaches the end of the device’s burstable address
space. This field’s 3-bit value can be written directly to the
Read Configuration Register bits 0–2 if the device is
configured for its maximum word width. See offset 28h for
word width to determine the burst data output width.
