Field Description
TX Buffer Related Status Information
TXFULL TX Buffer Full: Asserted when no more data can be stored.
TXNE TX Buffer Not Empty: Asserted when TX Buffer contains data.
RX Buffer Related Status Information
RXFULL RX Buffer Full: Asserted when RX Buffer is full.
RXNE RX Buffer Not Empty: Asserted when RX Buffer contains data.
AHB Buffer Related Status Information
AHBFULL AHB Buffer Full: Asserted when AHB buffer is full.
AHBNE AHB Buffer Not Empty: Asserted when AHB buffer contains data.
SFM Command Related Status Information
CONTMODE Continuous Mode: Asserted when last command was of type “Continuous Read Mode”
1
. It is
asserted at the end of the execution of the related command together with the QSPI_SFMFR[TFF]
flag.
AHB_ACC AHB Access: Asserted when the transaction currently executed was initiated by AHB bus.
IP_ACC IP Access: Asserted when transaction currently executed was initiated by IP bus.
BUSY Module Busy: Asserted when module is currently busy handling a transaction to an external flash
device.
