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 are 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
bites 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

Page Mode Read capability
bits 0–7 = “n” such that 2
n HEX value represents the number of
read-page bytes. See offset 28h for device word width to
determine page-mode data output width. 00h indicates no
read page buffer.
Number of synchronous mode read configuration fields that
follow. 00h indicates no burst capability.
Synchronous mode read capability configuration 1
Bits 3–7 = Reserved
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.

Number of device hardware-partition regions within the device.
x = 0: a single hardware partition device (no fields follow).
x specifies the number of device partition regions containing
one or more contiguous erase block regions.
