Reading the OTP Registers
The OTP Registers can be read from OTP-RA address. To read the OTP Register, first
issue the Read Device Identifier command at OTP-RA address to place the device in the
Read Device Identifier state (see

address offsets of the OTP Registers and Lock Registers. OTP Registers and Lock
Registers data is read 16 bits at a time.
Programming the OTP Registers
To program an OTP Register, first issue the OTP Register Program Setup command at
the device base address plus the offset address of the desired OTP Register location
(OTP-RA: see
Register data to the same OTP Register address. See
Bus Cycles” on page
20). Next, perform a read operation using the address offset corresponding to the
