Field
Description
CNTMDFB
Continuos Mode Bit Flash B: This bit is updated when a SFM Command is triggered.
0 The SFM Command triggered does not belong to the subset of Continuous Mode commands.
1 The SFM Command triggered does belong to the subset of Continuous Mode commands.
Refer to Section 35.6.6, Continuous Mode Commands, for details.
CNTMDFA
Continuos Mode Bit Flash A: This bit is updated when a SFM Command is triggered.
0 The SFM Command triggered does not belong to the subset of Continuous Mode commands.
1 The SFM Command triggered does belong to the subset of Continuous Mode commands.
Refer to Section 35.6.6, Continuous Mode Commands, for details.
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.
35.4.4.13 Flag Register (QSPI_SFMFR)
The QSPI_SFMFR register provides all available flags about SFM command execution and arbitration
which may serve as source for the generation of interrupt service requests. Note that the error flags in this
register do not relate directly to the execution of the transaction in the serial flash device itself but only to
the behavior and conditions visible in the QuadSPI module.
