Number of Protection register fields in JEDEC ID space.
“00h,” indicates that 256 protection bytes are available
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.
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

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
number of continuous synchronous burst 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 until 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 1Fh for word width to determine
the burst data output width.
Synchronous Mode Read Capability Configuration 2
