QSPI enable. When set, the QSPI initiates transfers in master mode by executing commands in the command RAM.
Automatically cleared by the QSPI when a transfer completes.The user can also clear this bit to abort transfer unless
QIR[ABRTL] is set. The recommended method for aborting transfers is to set QWR[HALT].
QSPILCK Delay. When the DSCK bit in the command RAM, is set this field determines the length of the delay from
assertion of the chip selects to valid QSPI_CLK transition.
Delay after transfer. When the DT bit in the command RAM sets this field, it determines the length of delay after the serial
transfer.
SPE
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 to by
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].
