can be generated if the ERRIE bit is set. The desynchronization flag (FRE) is cleared by
software when the status register is read.
26.6.8 I
2
S interrupts
Tabl e 93 provides the list of I
2
S interrupts.
26.6.9 DMA features
In I
2
S mode, the DMA works in exactly the same way as it does in SPI mode. There is no
difference except that the CRC feature is not available in I
2
S mode since there is no data
transfer protection system.
