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 Mode Read capability
bits 0–7 = “n” such that 2
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.
