Read OTP (ROTP)
The Read OTP (ROTP) instruction is used to read the 64 bytes OTP area in the QIO-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 QIO-SPI protocol instruction code,
address and output data are all parallelized on the four pins DQ0, DQ1, DQ2 and DQ3.
The dummy byte bits can not be parallelized: 8 clock cycles are requested to perform the
internal reading operation.
