Deserial Serial Peripheral Interface (DSPI)
In Slave Mode, the DSPI generates a trigger pulse on the MTRIG pin when a rising or falling edge is
detected on HT. Which edge that generates an output pulse is selected by the TPOL bit in the
DSPI_DSICR.
25.3 Memory Map and Register Definition
25.3.1 Memory Map
Register accesses to memory addresses that are reserved or undefined result in a transfer error. Write
access to the DSPI_POPR register also result in a transfer error.
Table 25-4 shows the DSPI memory map.
