Flag Register
| TFF | IP Command Transaction Finished Flag: Set when the QuadSPI module has finished a running IP Command |
| IPGEF | IP Command Trigger during AHB Grant Error Flag: Set when the following condition occurs: A write access occurs to the QSPI_IPCR[SEQID] field and the QSPI_SR[AHBGNT] bit is set |
| IPIEF | IP Command Trigger could not be executed Error Flag |
| IPAEF | IP Command Trigger during AHB Access Error Flag |
| IUEF | IP Command Usage Error Flag: Set when in parallel flash mode the execution of an IP Command is started with more than one pad enabled and the sequence pointed to by the sequence ID contains a WRITE or a WRITE_DDR command |
| ABOF | AHB Buffer Overflow Flag: Set when the size of the AHB access exceeds the size of the AHB buffer |
| AIBSEF | AHB Illegal Burst Size Error Flag: Set whenever the total burst size(size x beat) of an AHB transaction is greater than the prefetch data size |
| AITEF | AHB Illegal transaction error flag |
| ABSEF | AHB Sequence Error Flag: Set when the execution of an AHB Command is started with a WRITE or WRITE_DDR Command in the sequence pointed to by the QSPI_BUFxCR register |
| RBDF | RX Buffer Drain Flag: Will be set if the QuadSPI_SR[RXWE] status bit is asserted |
| RBOF | RX Buffer Overflow Flag: Set when not all the data read from the serial flash device could be pushed into the RX Buffer |
| ILLINE | Illegal Instruction Error Flag: Set when an illegal instruction is encountered by the controller in any of the sequences |
| TBUF | TX Buffer Underrun Flag: Set when the module tried to pull data although TX Buffer was emptyor the buffer contains less than 128bits of data |
| TBFF | TX Buffer Fill Flag: Before writing to the TX buffer, this bit should be cleared |
| DLPFF | Data Learning Pattern Failure Flag: Set when DATA_LEARN instruction was encountered in a sequence but no sampling point was found for the data learning patternin case only 8 bit data learning is requested for non DQS mode |
