I have a question which I hope you could answer.
I am creating a program that reads (Command: QOR (0x6B)) Flash on the ZC 706 Board from the QSPI Controller.
But I can not read the correct value.
When checking the waveform, the QSPI Controller outputs an extra 6 Cycle between Command + Address and Data Read Cycle.
We anticipate that the QSPI Controller is outputting Dummy Cycle.
QSPI Controller outputs Dummy Clock?
And, please tell me how to control it.

Thank you for your early response.
However, this problem was not solved.
This is a problem when unnecessary dummy bytes of 3 bytes are output when reading data of flash memory via QSPI.
I set the dummy byte of the LQSPI_CR register to 0, but I can not understand why the dummy byte is output at the time of reading.
Please tell me the register setting so as not to output dummy byte when reading.
