Queued Serial Peripheral Interface (QSPI) Module
16.2.2
Because the QSPI module only operates in master mode, the master bit in the QSPI mode register
(QMR[MSTR]) must be set for the QSPI to function properly. The QSPI can initiate serial transfers but
cannot respond to transfers initiated by other QSPI masters.
16.3
The QSPI uses a dedicated 80-byte block of static RAM accessible both to the module and the CPU to
perform queued operations. The RAM is divided into three segments as follows:

QSPI Data Output (QSPI_Dout)
