This field describes user-available OTP bytes.
Some are preprogrammed with device-unique se-
rial numbers. Others are user-programmable.
Bits 0-15 point to the OTP Lock byte (the first
byte).

The following bytes are factory preprogrammed
and user-programmable:
Bits 0 - 7 = Lock/bytes JEDEC plane physical low
address.
4
Bits 8 - 15 = Lock/bytes JEDEC plane physical high
address.
Bits 16 - 23 = n where 2n equals factory preprog-
rammed bytes.
Bits 24 - 31 = n where 2n equals user-programma-
ble bytes.
