Queued Serial Peripheral Interface (QSPI) Module
Correspondingly, a read at QDR returns the data in the RAM at the address specified by QAR[ADDR].
This also causes QAR to increment. A read access requires a single wait state.

The QDR, shown in
data from and to the QSPI RAM through this register. A read or write to QDR causes the value in QAR to
increment.
