10.8.2.4 DSPI Status Register (DSPIx_SR)
The DSPIx_SR contains status and flag bits. The bits are set by the hardware and 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 DSPIx_SR by writing a 1 to clear it (w1c). Writing a 0 to a flag bit has no effect.
