 I am using the evkmcimx6ull eval board that has a Micron MT25QL256ABA Qspi flash on it. I am trying to write to the non-volatile configuration register inside the Qspi flash. I believe I have the correct command sequence, 0x200404B1, but how do I send the data to program the register with? I have tried using the TX Buffer Data Register, but could not get it to write out the data, the reference manual states the TBDR is for the page programming commands. What buffer is used for register writes?
