QSPI_CS inactive level.
Halt transfers. Assertion of this bit causes the QSPI to stop execution of commands once it has
completed execution of the current command.
Wraparound enable. Enables wraparound mode.
0 Execution stops after executing the command pointed to by QWR[ENDQP].
1 After executing command pointed to by QWR[ENDQP], wrap back to entry zero, or the entry pointed
Wraparound location. Determines where the QSPI wraps to in wraparound mode.
0 Wrap to RAM entry zero.
1 Wrap to RAM entry pointed to by QWR[NEWQP].
0 QSPI chip select outputs return to zero when not driven from the value in the current command RAM
1 QSPI chip select outputs return to one when not driven from the value in the current command RAM
End of queue pointer. Points to the RAM entry that contains the last transfer description in the queue.
Completed queue entry pointer. Points to the RAM entry that contains the last command to have been
completed. This field is read only.
Start of queue pointer. This 4-bit field points to the first entry in the RAM to be executed on initiating a
transfer.
