1 The QSPI is in master mode. Must be set for the QSPI module to operate correctly.
Data output high impedance enable. Selects QSPI_Dout mode of operation.
0 Default value after reset. QSPI_Dout is actively driven between transfers.
1 QSPI_Dout is high impedance between transfers.
Transfer size. Determines the number of bits to be transferred for each entry in the queue.

Clock polarity. Defines the clock polarity of SCK.
0 The inactive state value of QSPI_CLK is logic level 0.
1 The inactive state value of QSPI_CLK is logic level 1.
Clock phase. Defines the QSPI_CLK clock-phase.
0 Data captured on the leading edge of QSPI_CLK and changed on the following edge of
1 Data changed on the leading edge of QSPI_CLK and captured on the following edge of
Baud rate divider. The baud rate is selected by writing 0, or a value in the range 2–255. 1 is not a
valid value. A value of zero disables the QSPI. The desired QSPI_CLK baud rate is related to
CLKIN and QMR[BAUD] by the following expression:
QSPI_CLK.
QSPI_CLK.
QMR[BAUD] = SystemClock / [2 × (desired QSPI_CLK baud rate)]
