Write collision access error enable. A write collision occurs during a data transfer when the
RAM entry containing the command currently being executed is written to by the CPU with
the QDR. When this bit is asserted, the write access to QDR results in an access error.
Abort access error enable. An abort occurs when QDLYR[SPE] is cleared during a transfer.
When set, an attempt to clear QDLYR[SPE] during a transfer results in an access error.
Reserved, should be cleared.
Abort lock-out. When set, QDLYR[SPE] cannot be cleared by writing to the QDLYR.
QDLYR[SPE] is only cleared by the QSPI when a transfer completes.
Write collision interrupt enable. Interrupt enable for WCEF. Setting this bit enables the
interrupt, and clearing it disables the interrupt.
Abort interrupt enable. Interrupt enable for ABRT flag. Setting this bit enables the interrupt,
and clearing it disables the interrupt.
Reserved, should be cleared.
QSPI finished interrupt enable. Interrupt enable for SPIF. Setting this bit enables the
interrupt, and clearing it disables the interrupt.
Reserved, should be cleared.
Write collision error flag. Indicates that an attempt has been made to write to the RAM entry
that is currently being executed. Writing a 1 to this bit clears it and writing 0 has no effect.
Abort flag. Indicates that QDLYR[SPE] has been cleared by the user writing to the QDLYR
rather than by completion of the command queue by the QSPI. Writing a 1 to this bit clears
it and writing 0 has no effect.
Reserved, should be cleared.
QSPI finished flag. Asserted when the QSPI has completed all the commands in the
queue. Set on completion of the command pointed to by QWR[ENDQP], and on
completion of the current command after assertion of QWR[HALT]. In wraparound mode,
this bit is set every time the command pointed to by QWR[ENDQP] is completed. Writing
a 1 to this bit clears it and writing 0 has no effect.
