Read OTP (ROTP)
The Read OTP (ROTP) instruction is used to read the 64 bytes OTP area in the DIO-SPI
protocol. The instruction functionality is exactly the same as the Read OTP instruction of the
Extended SPI protocol; the only difference is that in the DIO-SPI protocol instruction code,
address and output data are all parallelized on the two pins DQ0 and DQ1.
The dummy bits can not be parallelized since these clock cycles are requested to perform
the internal reading operation.

Write Enable (WREN)
The Write Enable (WREN) instruction sets the Write Enable Latch (WEL) bit.
Apart form the parallelizing of the instruction code on the two pins DQ0 and DQ1, the
instruction functionality is exactly the same as the Write Enable (WREN) instruction of the
Extended SPI protocol.
