Master mode enable.
0 Reserved, do not use.
1 The QSPI is in master mode. Must be set for the QSPI module to operate correctly.
Reserved, must be cleared.
Transfer size. Determines the number of bits to be transferred for each entry in the queue.
Clock polarity. Defines the clock polarity of QSPI_CLK.
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 QSPI_CLK.
1 Data changed on the leading edge of QSPI_CLK and captured on the following edge of QSPI_CLK.
Baud rate divider. The baud rate is selected by writing a value in the range 2–255. A value of zero disables the QSPI.
A value of 1 is an invalid setting. The desired QSPI_CLK baud rate is related to the internal bus clock and
QMR[BAUD] by the following expression:
QMR[BAUD] = f
