25.3.2.4 DSPI Status Register (DSPI_SR)
The DSPI_SR contains status and flag bits. The bits reflect the status of the DSPI and indicate the
occurrence of events that can generate interrupt or DMA requests. Software can clear flag bits in the
DSPI_SR by writing a ‘1’ to it. Writing a ‘0’ to a flag bit has no effect. This register may not be writable
in MDIS Mode due to the use of power saving mechanisms.
